PRDM9: meiosis and recombination
Introduction
PRDM9 is a gene on human chromosome 5 with a very peculiar history. Its primary function -- after many false starts -- has only recently become clear: scanning the genome with its terminal zinc finger array to locate and mark recombination hotspots with its histone methylase where its transcription factor domain can direct additional proteins to initiate the double stranded breaks needed for meiosis. Some level of recombination between homologous chromosomes is essential to proper alignment and separation into daughter cells as well as for bringing favorable alleles onto the same haplotype for adaptive evolution.
Such a mission-critical protein is typically highly conserved. However this is not the case here at all. Indeed, it proves exceedingly difficult to find a comprehensive set of PRDM9 orthologs even in the 39 sequenced placental mammalian genomes available on 15 July 2011, with immense confusion in the literature over paralogs, lost copies, pseudogenes, and similar composite domain proteins having only very distant homology. PRDM9 and its parent gene PRDM7 do not have a full-length counterpart in marsupials, monotremes, birds or earlier diverging vertebrates -- perhaps unusual in the whole proteome context but not for zinc finger proteins.
Rapid evolution of this gene subfamily occurs at the amino acid level, especially in zinc finger number and in the four residues responsible for recognizing a specific dna trinucleotide. This is not coincidental to the role in meiosis: the process tends to destroy its recombination hotspots by biased gene conversion. Since recombination is essential, new hotspots must emerge. The race is then on for PRDM7 or its spun-off PRDM9s to rapidly evolve and define new histone markup sites.
This rapid evolution could cause breeding incompatibility between populations in the F1 generation (meiosis arrest for lack of cross-overs, notably between chrX and chrY) and thus be central to the process of speciation. However the evolution of the hotspot-defining gene takes very different forms in different mammalian lineages. In effect each major clade of placentals is evolving a qualitatively different mating system, taking its most extreme form in pecoran ruminants with 6 PRDM9 genes. This differentiation follows upon the very different structure and gene content of sex chromosomes between monotremes, marsupials and placentals which in turn are much different from those of the amniote ancestor..
Syntenic relationships can help resolve gene duplication events during mammalian evolution. Here the chromosomal gene order TUBB3+ AFG3L1+ GAS8+ has stably existed since the stem amniote emerged 310 million years ago, with the arrangement TUBB3+ AFG3L1+ GAS8+ PRDM7- qTer arising in placental mammals prior to Afrothere divergence (ie, between 102-125 myr ago) and maintained there since over billions of years of observable branch length. PRDM9 however is found in many syntentic contexts, depending on clade and the various segmental duplications giving rise to these secondary copies.
From the perspective of comparative genomics, PRDM7 is the fundamental gene, not the disparate collection of genes lumped under PRDM9. At different times in different placental clades, PRDM7 spun off segmental duplications of itself to other sites in other chromosomes, probably because of its susceptible location at the extreme q arm of an autosomal chromosome. Because PRDM7 has stayed at its site adjacent to GAS8, it is possible to say unambiguously which of two initially identical copies is the parent gene. Because of this history, the 'PRDM9' genes do not form a distinct subtree within the overall two gene tree under phylogenetic algorithms but instead associate more closely with their parental PRDM7 parent.
These paralogous copies -- despite all being called PRDM9 -- are not orthologous outside their species clade of origin. Orthology requires (by long-standing definition) vertical descent from a common gene in the last common ancestor of two species. Here primate PRDM9 are descended from a common gene (namely the recent duplicate of PRDM7 in the stem preceding speciation) but 'PRDM9' in other clades arose from different duplications at different times during placental mammal evolution and so are not orthologous to primate PRDM9 (not vertically descended from a common PRDM9 in their last common ancestor).
Such copies are sometimes called in-paralogs within a species and co-orthologs across species. However these terms are topologically unstable (depend on the extent of species included in the gene tree) unlike the terms ortholog, paralog and homolog which are well-defined. Composite domain proteins such as PRDM7 give rise to whole new levels of terminological confusion as each domain has a long, complex and separate history of duplication and shuffling.
Comparative genomics in placental mammals
In euarchontoglires, a segmental duplication of PRDM7 occurred in a stem catarrhine primate and descended through speciation events to contemporary old world monkeys and great apes. This second copy (PRDM9) relocated to and stayed within a cadherin gene complex on a different chromosome. PRDM7 persisted at its original ancestral location but became an overt pseudogene in some lineages (rhesus, gibbon, gorilla, chimp and human) but not so clearly in others (orangutan). Earlier diverging primates such as lemurs, tarsier and new world monkeys have a single PRMR7 gene adjacent to GAS8. Tree shrew has unsatisfactory coverage in this region (six exons spread out over two contigs and 3 unassembled traces, a string of Ns in the terminal zinc finger domain, and undetermined synteny).
Although an obvious pseudogene, human PRDM7 is sometimes treated as a functional gene with 'isoforms'. However exon 9 of the reference sequence hg18 contains an internal direct tandem repeat of 88 nucleotides that throws off the reading frame and subsequent splice to exon 10, which itself has a frameshift (GGGG to GGG) in the second of its three zinc fingers. The protein is incorrectly described at NCBI, SwissProt and UCSC -- zinc fingers translated into the wrong reading frame cannot possibly form a stable fold, much less recognize a nucleotide sequence. Given the common comparative genomics context of duplication followed by subsequent pseudogenization (of either parent or duplicate), this feature is unquestionably a pseudogene whether it is still transcribed or not. Pseudogenization likely predated divergence of bushman and neanderthal and apparently independently of those events in other primates.
Rodents and lagomorphs have no counterpart to PRDM9, though the situation is confused by later chromosomal rearrangements (no affirming homolog or even debris adjacent to GAS8 or cadherin). The mouse gene is then orthologous to primate PRDM7, not PRDM9. The rat gene occurs in the same syntenic context as mouse; other rodent genomes are too incomplete for synteny to be assessed. Rabbit has two apparent PRDM7, called here PRDM7a and PRDM7b; neither copy is syntenic to mouse/rat or any other mammal. The pika genome is too incomplete to determine whether this duplication predated their divergence. Overall the data is consistent with a single PRDM7 locus in the last common ancestor of primate and rodent. It would be vastly more useful to complete genomes already begun than to embark on incomplete sequencing of an additional 10k vertebrate genomes.
Laurasiatheres have a quite different history of gene duplication. Most species simply retain the ancestral condition of a single PRDM7 gene adjacent to GAS8. Vampire bat (but not brown bat) has an additional segmental duplication to a novel location that is today a pseudogene. Dog inexplicably has a PRDM7 pseudogene but no PRDM9 despite a rather complete assembly, even as other carnivores (cat, panda, ferret), insectivores, perissodactyls and early-diverging artiodactyls (alpaca, pig, dolphin) have a conventional single PRDM7 gene (though some of these have too few zinc fingers to recognize sufficiently long dna motifs to delimit hotspots).
Carnivores -- but not bats or horses -- have an intervening cadherin gene between GAS8 and PRDM7. This rare genomic event is not the ancestral state but is unfortunately too restricted in distribution to resolve the status of Pegasoferae:

Pecoran ruminants (cow, sheep, muntjak) present a vastly more complicated situation. Cows -- even in the revised assembly -- have a PRDM7 pseudogene adjacent to GAS8 accompanied by 5 PRDM9 copies in other locations (all distinct from the primate cadherin secondary site). This is neither a recent development nor an artifact of domestication because a similar expansion is seen in provisional assemblies of sheep and muntjak (wild deer) but not dolphin, pig or vicuna, dating the expansion to stem pecoran ruminant. It is not clear which if any of these gene copies play a role in recombination -- the primate paradigm for meiotic markup is not immediately applicable to these species.
Atlantogenata (Afrotheres + Xenarthra) have yet another history. Elephant (best of five available assemblies) has three loci: an old PRDM7 pseudogene in GAS8 syntenic position, a seemingly functional PRDM9a with 12 terminal zinc fingers and novel syntenic location, and a fairly recent pseudogene PRDM9b. A dna assembly from fossil mammoth shows the same three genes with the same pseudogenization pattern. Although the sequences diverged separately after speciation, three identical inactivating mutations occur in both mammoth and elephant but not hyrax, thus dating gene loss relative to their speciation. This is shown for exon 9 below:

Marsupials and platypus: the mystery of exon 5
Tracking PRDM7 back to marsupials and beyond presents significant uncertainties. The three available marsupial assemblies are seriously incomplete, causing gene prediction problems when exons are spread over multiple small contigs, which further do not provide syntenic validation. Domain linker regions have weak amino acid conservation and so fail to give blast matches to placental queries, a problem exacerbated for short exons and pseudogenes (opossum). No expression data exist to bridge uncertain regions, meaning missing exons cannot be located nor exons in different contigs definitively connected. Because the domains here occur widely in other combinations in other proteins, a full length marsupial sequence is critical to testing whether the domain shuffle resulting in PRDM7 and PRDM9 was a placental innovation.
The most favorable situation occurs in the Monodelphis domestica assembly. Here eight of the ten expected exons (1 and 5 are missing) are readily located in a single assembly region of length 33,449 bp with a single gap (estimated at 270 bp). It is not surprising that exon 1 cannot be located because it has no known domain or reason for fixed length and is diverging rapidly in placentals. However locating exon 5 is important for distinguishing between two adjacent small genes evolving into a single fused gene only in the placental branch versus a full length gene already present in the last common ancestor.
Unless exon 5 lies within the assembly gap, it should be locatable in the 25,548 bp separating exon 4 and exon 6 (of which 8,263 bp remains after application of RepeatMasker). However blastx against a panel of 54 exon 5 sequences from placental mammal fails to give any suggestion of match, despite plausibly adequate length (all placental exon 5 sequences have 52 amino acids).
Gene prediction tools such as GenScan, NScan, Ensembl and Gnomon give useless results because they neglect comparative genomics: a few exons are correctly predicted but are otherwise embedded in time-wasting rubbish. The poor reliability of these tools does not justify GenBank clutter (eg XM_001369137) for their predictions. The 46-species whole genome alignment at UCSC (starting with PRDM7/9 'ProteinFasta' link at the description page) is a better starting point.
Here it should be noted that exon 5 has not diverged especially rapidly from the last common ancestor of placentals. Aligned to human, the full range of sequences has overall identity of 69%. Exon 5 has a number of invariant and semi-invariant residues, only possible over this time span if maintained by selective pressure. Thus it has some function even though it contains no known Pfam domains and has no crystallographic structure match. Because exon 4 has a splice donor of phase 0 and exon 6 a splice acceptor of phase 2, exon 5 in marsupials must take the form 0 xxxxxxxx 1 to conserve reading frame. This rules out non-use of exon 5 in marsupials (alternative splicing) followed by mutational decay to unrecognizability.
The opossum gene is peculiar in that 7 of the 8 exons available are quite conventional in sequence but the terminal zinc finger exon is completely broken up by frameshifts and stop codons and barely recognizable. The other exons return only PRDM7/9 as significant matches when back-blasted against the human genome establishing that they have not been confused with the many hundreds of partial homologs with KRAB, SSXRD, PR (SET) or C2H2 domains.
The Sarcophilus harrisii assembly is missing the same two exons but has a conventional terminal exon with an intact zinc finger region of seven repeats (with two distal frameshifts however). Here exons 2 occurs in contig AFEY01202902 and exons 3-4 in AFEY01156721 with 1,436 bp left over to host exon 5; exons 6-10 are found in a third contig AFEY01386448 with 8,331 bp available upstream for exon 5. It is not known whether these contigs would be adjacent in more complete assembly.The six exons comparable between tasmanian devil and opossum are 82% identical to each other as proteins and 67% identical to those of human, not indicative of anomalous or especially rapid evolution in the context of entire proteome rates.
The Macropus eugenii (wallaby) assembly is least complete, with no contig containing more than a single exon. Here exons 1, 4, 5 and 8 are missing altogether but the terminal zinc finger exon is intact with 7 C2H2 domains. It is worth noting that the exon 10 is so long and distinctive with its phase 2 reading frame and early zinc finger that there is no possibility of confusing it with those of homologs (HKR1, ZNF133, ZNF169, ZNF343, ZNF589 in human).
If marsupials had a markedly (or even totally) different exon 5 of form 0 xxxxxxxx 1, it should emerge from a tblastx comparison of the regions between exons 4-6. However no plausible candidate emerges. This implies orthology despite the assembly gaps and missing exon 5, ie the last common ancestor to marsupials and placentals had a full length PRDM7-type gene. It is uncertain whether these should be connected up into a single gene with the later exons -- the whole issue here is timing of the final gene shuffle.
The situation in platypus is curious. Only distal exons 6-10 can be reliably recognized in the current assembly, ie KRAB, SSXRD and exon 5 are missing but the knuckle, PR and zinc finger domains are present with 3-4 repeat units. However the early zinc finger in the last exon is not present. Yet the best backblast to human is still PRDM7/9. These exons occur in two tandem copies on the same strand but differ significantly from each other and so do not represent mis-assembly duplications. The intervening area is gapless so the missing exons should be locatable if present.
However they are not. Upon blastx of the repeatmasked sequence against Genbank tetrapod sequences, no matches occur, other than three worthless platypus gene models (XP_001507240, XP_001509482, XP_001509433) that predict earlier exons which however are wholly lacking in any support in any other species. Thus it appears that the gapless region does not contain any counterpart to exons 1-5 of theran mammals. Either this region has been lost in platypus or it is a stand-alone shorter distal version of PRDM7/9. The first identifiable exons begins with the expected phase 2 reading frame in both tandem copies and do not contain an in-frame methionine upstream prior to a stop codon. Hence there must be at least one earlier exon. However tblastx of the appropriate regions of repeatmasked marsupial and platypus again does not identify noteworthy peptide candidates.
Perhaps the corresponding ancestral region was shuffled together with a gene providing the proximal regions in the theran branch only, giving rise to the full length gene there. However tblastn queries of the platypus assembly, while locating numerous appropriate KRAB_A domains with the correct 0 xxxxxxxx 1 reading frame that backblast to other human proteins, do not find counterparts of the exon 1-5 region beyond exon 2. Hence there is no obvious donor for the proximal half of PRDM7/9.
Given that the PRDM and zinc finger families are greatly expanded with extensive domain shuffling in mammals with difficulties already tracing back PRDM7/9 to marsupials and monotremes, it comes as no surprise that bird, lizard and frog genomes shed no further light on the evolution of this gene. The situation in non-placental mammals could theoretically be resolved by sequencing transcripts, but these are exceedingly rare for PRDM7/9 even in placentals and so will not emerge unless explicitly sought.

Distal domain combination already formed by fish ancestor
Various additional sequences are relevant to understanding the curated placental mammal PRDM7/9 set. For example, the neanderthal genome despite being very far from satisfactory coverage can provide a PRDM9 sequence derived from the human reference sequence using non-synonymous SNPs reported in the corresponding UCSC browser track. The changes reported in the zinc finger domain (R HDL S R) may be enough to have created somewhat of a species barrier, though this involves comparing a fossil sequence to a contemporary human (which are today themselves quite variable). Similarly, the bushman genome sequence might yield an intermediate outgroup, though that assembly (like so many others) remains elusive.
Terminal sequences for 9 additional species of murid rodents have been determined but these have limited value for comparative genomics because they do not even cover the entire terminal exon and their syntenic contexts (and thus homological relationships) were not established. The single individual sequenced may not be representative of the overall population in the zinc finger region (based on the extensive diversity observed in human), diminishing their utility for predicting species barriers. These genes are most likely PRDM7 orthologs only secondarily related to the catarrhine primate PRDM9 set, ie descended from the unique locus present in stem euarchontoglires whereas the latter duplicated from a stem old world monkey PRDM7. It is worth noting that the reported sequences are very orderly and lack the overall chaos of frameshifts and stop codons so often seen in this gene family. The protein accessions are here.
A zebrafish protein put forward as an ortholog to placental mammal PRDM9 seems implausible given that birds, lizard and frog lack notable homologs. It lacks close counterparts in other species of fish with determined genomes and is not syntenic to mammalian gene locations. Thus it might represent an independent gene shuffle that resulted in a similar concatenation of domains (parallel evolution) . However both piecewise and whole back-blast to mammal call up only PRDM7/9 and the closely related PRDM11, suggesting orthology of the parts. The protein lacks the KRAB and SSXRD domains but contains a standard knuckle, PR(SET), early ZNF finger and ZNF repeat domain (all in exons phased identically to human). The repeat region is fairly chaotic with only moderate resemblance in its details to mammalian zinc fingers. Related genes are found in salmon, trout, catfish and minnow but not stickleback, fugu, tetraodon or medaka. Transcripts are exceedingly common in contrast to mammals. The missing KRAB and SSXRD domains are believed critical in recruiting other essential proteins to the hotspot in the only systems with experimental data (mouse and human).
Reported PRDM9 orthologs in early diverging bilatera such as Lottia, Capitella and Nematostella can be dismissed as independent occurrences of common ancient domains. None of these domains are mammalian innovations -- PR(SET) traces back to bacterial methylases and zinc fingers also have a long and complex history. Without conservation of all mammalian domains, exon phasing, syntenic chromosomal location and demonstration of descent from a single gene in the last common ancestor, there is no basis for calling such genes orthologous nor assuming they function similarly in meiosis or illuminate mammalian PRDM7/9 evolution in any way. Widespread expression in testes is actually not supportive as it conflicts with the mammalian expression pattern. How could such a fundamental capacity be lost (and replaced by a non-homologous system) so many times in so many other lineages-- all of which have obligatory meiosis?
It thus appears that while the core distal domains (terminal five exons) of PRDM7/9 came together long ago, the function may have been inessential because numerous lineages subsequently lost any counterpart. This core domain persisted however into the common ancestor with monotremes, with the full length gene only coming together by marsupial divergence (or with more certainty, in stem placental).

Comparative genomics: sequence availability
As of mid-April 2011, some 61 PRDM7 and PRDM9 genes from 36 species can be recovered from placental mammal genome projects. The encoded proteins are compiled here as tab-delimited pdf text that will paste cleanly into rows and columns of a spreadsheet such as excel, and as exon-by-exon gene models in the Curated reference sequences section below.
Of these 61 genes, 18 are pseudogenes in various states of degeneration. There has been no gain or loss of introns -- all have the same identically intronated ten exons. No retroprocessed genes occur despite transcription in germline tissues. Because many genomes are incomplete, 83 exons of the 610 expected are apparently located in coverage gaps or are too short and diverged to be recognizable.
The table below shows the number of zinc fingers in the second column, phylogenetic clade in the third, and adjacent gene (synteny) in the fifth.
The number of zinc fingers is quite variable in human and likely so in all species; the table provides that of the individual selected for genome project which may not be repesentative of the species. These zinc finger arrays have been corrected in low coverage genomes for common sequencing errors -- frameshifts and premature stop codons arising from nucleotide run length mis-calls (eg, ggggg interpeted as gggg).
Pseudgenes are sometimes obvious (large deletions, reading frame errors at multiple locations, stop codons in early exons, amino acid substitutions not corresponding to the conservation profile) but otherwise can be difficult to distinguish from assembly error or a bad allele of a usually intact gene in the population (possibly a balanced polymorphism that reduces copy number). A pseudogene can continue being transcribed for tens of millions of years after losing all functionality at the protein level. That is moot here because PRDM7 and PRDM9 are barely represented in the tens of million mammalian transcripts at GenBank.
The PRDM7 genes are all orthologous in the classical sense (as can be seen by adjacency to the unrelated gene GAS8) but the PRDM9 genes arose as different lineage-specific segmental duplications so are orthologous only when shared within a well-defined phylogenetic clade.
- PRDM7: genes with ancestral location GAS8 synteny

Comparative genomics of PRDM9 and PRDM7
PRDM9 is one of many human proteins sharing a set of common domains, as well as various multiplicities of the zinc finger domain C2H2. The diagram at left shows an effort at organizing these into phylogenetic tree according to structural considerations of the SET domain these proteins all share.
The traditional SET domain is too small for an enzyme with distinctive substrates so flanking sequence must be added despite its lack of apparent conservation. Using S-adenosyl methionine, PRDM9 places the third methyl group only on the fourth position lysine in mature histone H3 (which is actually position 5 prior to iMet removal: MARTKQTARK...), one of many such epigenetic methylases in the human genome. The histone recognized by such methylases correlates poorly with evolutionary grouping by SET domain (figure).
The upper left corner shows the variability in domain structure. While PRDM9 and PRDM7 share the same domains (an upstream KRAB domain is not shown), of PR-class homologs, PRDM11 shares only the SET domain despite nesting deep within the PRDM9 subtree. PRDM4 has both the SET and C2H2 domains, possibly sharing the early C2H2 domain in an exon beginning with a phase 2 splice acceptor (as shown in reference sequence section). Overall however, PRDM9 and PRDM7 have no full length homologs with matching exon structure. Even the SET domain is intronated differently within PR-class proteins (with the sole exception of PRDM11), suggesting either ancient divergence or unusual evolution. These incongruities may have arisen from domain shuffling, gain and loss.
The human PRDM9 sequence below is annotated in color for domains relative to exon breaks. The protein can be best understood in terms of concatenated domains, not all of which may be present in antecedent and descendant homologs. The first two domains KRAB and SSXRD interact with transcription factors.
Each C2H2 domain -- so named for two cysteines and two histidines liganding to a structural zinc ion -- recognizes a specific trinucleotide (more or less) and so concatenated in a large array recognize specific binding sites along the genome, though tolerance of nucleotide variability and synergistic effects between adjacent units make it difficult to read out these sites precisely, despite immense efforts.
The concatenated C2H2 domains, conserved at the amino acid level so necessarily similar at the dna level, are prone to replication slippage. This process can give rise to point mutations as well as leading to a peaked distribution of repeat number rather than to a single number. Many other unrelated genes with internal repeats (such as the octapeptide region of the prion gene PRNP) are also affected by replication slippage. Such proteins regions are conveniently identified genomewide by mRNA dot plots.
The C2H2 domains generally reside in a long distinctive terminal exon of splicing phase 2 that has been shuffled over mammalian evolutionary time into various contexts. Concepts such as paralogy and orthology need piecewise definitions in these composite proteins. Synteny (gene adjacency) plays a major role in reliably deconstructing events in specific lineages.
Here the unrelated single-copy conserved gene GAS8 plays an important role. PRDM7 occurs immediately distal to it on the negative strand, making the two genes are convergently transcribed). PRDM7 is otherwise the last gene on the q arm of its chromosome in many species which may predispose it to copy number dispersal events. PRDM9 is not consistently located within placental mammals, suggesting independent relocation events.
Both PRDM9 and PRDM7 contain a seldom-mentioned C2H2 domain early in the exon annotated by SwissProt and readily found by the online domain tools regardless of species. This domain conserves the four critical residues needed for zinc binding (and so the associated fold) but lacks the terminal cap TGEKP which otherwise serves to lock down a C2H2 zinc finger after it has scanned along genomic dna to an appropriate trinucleotide. The function of this early domain and the following 112 residues are unknown -- no homologous 3D structure has ever been determined.
The first C2H2 of the main repeat region is proximaly degenerate, beginning in VKY in all species (instead of YCE). The tyrosine cannot plausibly replace the usual cysteine for zinc binding though the other three needed residues are present. This domain ends in a typical cap region TGEKP. Humans are the exception here where the conserved helix-ending proline has been replaced with leucine in the reference human genome with unknown functional consequences.

Different segmental duplications relate PRDM9 and PRDM7
In humans, PRDM9 and PRDM7 are related by a 26 kbp segmental duplication that begins about 8 kbp upstream of the start codon and continues through most of the 3' UTR. Since the retroposon patterns are nearly identical, the duplication must be fairly recent. The overall percent identity of non-coding dna is about 93%, again inconsistent with either early (within stem placental or late divergence (post-chimpanzee). The duplication contains a potentially diagnostic 1845 bp retroposon-free region upstream of the first coding exon.
Note PRDM7 is situated at the extreme tip of chromosome 16q, perhaps predisposing it to chromosomal copy number rearrangements. The syntenic context is TUBB3+ DEFB+ AFG3L1+ DBNDD1- GAS8+ PRDM7- qTel, meaning it is transcribed convergently with GAS8, a non-homologous highly conserved single copy gene often detectable even in low coverage genomes in the small contig containing PRDM7. This association has been extremely stable over boreoeutheran placental mammal evolutionary time and so serves to reliably define PRDM7 orthologs and their spin-off copies. Elephants also have a gene pair similar to human PRDM9 and PRDM7. The former is at a syntenically novel site but the latter is an old pseudogene but still detectably adjacent to GAS8 in opposite orientation. It thus follows that 'PRDM9' in elephant is an independent earlier spin-off of its conventional PRDM7 gene. This is consistent with telomeric susceptibility to repeated rearrangements.
Recall here the actual definition of gene orthology: two genes in two species are orthologous if they are vertically descended from the same gene in their last common ancestor. Here the LCA of human and elephant is ur-placental mammal which had PRDM7 but no PRDM9. The two PRDM9 genes are thus not descended from a common ancestral PRDM9 gene but from parallel gene duplications of a common PRDM7 gene at different times in different clades during the course of mammalian speciation. Such genes are called in-paralogs within a given species and co-orthologs across them.
The syntenic context of PRDM9 is quite variable, supporting the scenario of multiple origins. This context can be used to count the number of distinct segmental duplications of PRDM7. For example, in humans, PRDM9 basically lies in a retroposon-rich gene desert but is eventually flanked by two pairs of cadherin genes at the much larger scale of 7 mbp. In rhesus, these same genes are seen (with some minor rearrangements), establishing that this PRDM9 segmental duplication preceded the divergence of old world monkeys.
Marmoset has a seemingly functional PRDM7 in the usual position facing GAS8, still at the extreme end of chromosome 20. The cadherin cluster is intact on chr2:178,954,165-180,696,523. However Blastx of the intervening dna -- which is similar in size to rhesus and human so not suggesting large deletions -- shows not even a suggestion of an old PRDM9 pseudogene. The assembly is gapless here. and Blastx is sensitive enough to detect very old pseudogenes provided they decayed by small indels and nucleotide substitutions. Thus it appears that PRDM7 never duplicated in marmoset -- placing that even in the stem to old world monkeys (or prior to tarsier divergence -- that assembly has poor coverage). Note that the marmoset PRDM7 has a respectable terminal zinc finger array of twelve units, enough to specify 36 bp.

Lemurs present a new complication. The Otolemur assembly has two distinct and seemingly functional PRDM7 copies (each with seven zinc fingers) containing GAS8 end-sequence in expected opposite orientation. One of the GAS8 copies appears to be a pseudogene. This represents a new type of lineage-specific segmental duplication. There is no sign of PRDM9. The other lemur with an assembly, Microcebus murinus, has but a single copy, again with seven zinc fingers. The only relevant contigs (ABDC01433247 and ABDC01371462) contain no coding syntenic information so this gene cannot be assigned to PRDM7 with certainty.
The tree shrew assembly, like tarsier, has low coverage and only blast matches to zinc finger arrays that cannot be assigned to the PRDM family. This cannot be totally attributed to low coverage because many ordinary genes are satisfactorily represented in these species. Other issues such as telomeric position, gene copy number (mobility), pseudogenization, deletional loss, chimerization, and individual heterozygosity must be affecting recovery of PRDM9 gene models in these species.
Moving on to laurasiatheres, Bos taurus presents a much more complicated situation. First, the GAS8 locus on chr18 contains the first two exons of a PRDM7 pseudogene in expected orientation but distal regions of the gene are completely deleted. The cadherin locus on chr20 is also intact but the 2.6 mbp region between CDH12 and CDH10 contains no indication of PRDM9, consistent with that segmental duplication being primate-specific and PRDM7 being the older parental location. This holds in the Baylor 4.0 assembly carried at UCSC, the Baylor 4.2 assembly, and the alternative assembly of the same data, UMD3.1. The latter two can be queried by the genomic blast server at NCBI.
A third locus on chr 1 hosts an unreviewed GenBank pipline entry called PRDM9, derived as NW_003053109 from the alternative bovine assembly UMD3.1 Staff corrected an unspecified frameshift to fix the reading frame -- a dangerous practise in a gene family so prone to pseudogenization. The gene, called PRDM9a here, resides on the extreme end of chromosome 1 and differs from the Baylor 4.0 assembly at two amino acids outside the zinc finger region. The syntenic context here is novel: EFHB- RAB5A+ PCAF+ ZNF596- PRDM9a- which corresponds overall to human chr 3. The juxtapositioning of two zinc finger proteins on the same strand causes PRDM9 alignments to extend spuriously into the 12 zinc fingers of ZNF596, jumping over its 5 earlier coding exons.
ZNF596 contains a KRAB domain but no SET methylase. Humans encode a best-blast protein of the same assigned name on chr 8 (77% identity). Note the early exons of ZNF596 can be added to end of PRDM9a to form an artificial probe for this association in other species, though the two genes have a 43,400 bp spacer in cow, which is large relative to contig size in low coverage assemblies. The sole fragmentary transcript from yak testis (EF432551) is nearly identical to this PRDM9a, suggesting that the gene -- and perhaps its syntenic location -- became established prior to yak-cow divergence and is still functional. However its array of seven zinc fingers could recognize at most a region of 21 bp.
ZNF596 did not arise from a PRDM9-like gene through loss of the SET domain, though it is one of the better matches within the large zinc finger family. Excluding the zinc finger domain, ZNF343, ZNF133 and ZNF169 provide much higher blastp scores, as they also do just comparing the zinc finger arrays. The juxtaposition of ZNF596 and PRDM9a is likely coincidental rather than a consequence of inhomogeneous recombination between zinc fingers bringing PRDM9 to this site.
The fourth PRDM9 locus of interest, called here PRDM9b, is still not mapped to any bovine chromosome. It resides in contig DAAA02065087 in the UMD3.1 assembly and is temporarily assigned to chr Un.004.649 at Baylor assembly. Here the reading frame in exon two can be restored if a run of 5 A's is corrected to 6 A's. That is done here in the reference sequences because this is typically just sequencing error. The protein has a full set of domains KRAB SSXRD SET C2H2 with a moderate zinc finger array of five. Synteny cannot be determined in chr Un features which can simply pool unrelated unplaceable contigs into a manageable unit. Flanking dna in DAAA02065087map to several places in the cow genome, suggesting this feature has copy number attributes, perhaps of telomeric repeat type. PRDM9b is not a recent feature because it differs at a considerable number of amino acids from other PRDM9 in the cow genome. These substitutions avoid highly conserved residues, not consistent with early pseudogenization. PRDM9b is capable of histone marking but it is not clear whether that has functional significance to meiosis.
Yet another locus in the Baylor 4.0 assembly, called PRDM9c here, could not initially be placed on a cow chromosome. While such features are often assembly artefacts, this one is supported by a transcript from 4-cell embryos (GO353654) consistent with a role in or after meiosis. In UMD3.1, this gene has been placed on chr X. Despite a very large contig, no zinc fingers occur in any reading frame, suggesting that the gene was transferred here without the last exon (or it subsequently got deleted). In any event, the penultimate exon does not have a phase 1 splice donor in expected position and so terminates at the next stop codon downstream. The protein retains the KRAB, SSXRD and SET domains but does not possess the ability to scan or bind dna. It has accrued various amino acid substitutions relative to other bovine that rule out recent establishment.
Finally, two additional genes, denoted PRDM9d and PRDM9e here, are located as a parallel tandem pair in a higher quality region of bovine chr X. These are 96% identical as proteins, consistent with one being derived fairly recently from the other. Synteny here will not be informative until other ruminant genomes become available.
Overall the situation in cow is very different from primates and rodents. Results there about the function of single-copy autosomal PRDM9 gnes in meiosis markup can scarcely be carried over to a species with five seemingly intact genes, three of which are on chr X (which intriguingly has the very limited pseudoautosomal region on chr Y where it can cross over).
The cow situation cannot be limited to the Hereford breed used for the genome project because the PRDM9 are too diverged from one another outside the zinc finger region. Indeed there is some suggestion from non-NCBI sheep genome that it too has many of these copies. However other cetartiodactyl genomes (dolphin, pig and alpaca) and other laurasiatheres (panda, dog, cat, shrew, bats) do not show these copies, suggesting that this complexity could be limited to pecoran ruminants. All-vs-all blastp percent identities are consistent with this, though rates of evolution in this gene family are hardly typical.This cannot be resolved with cow genome alone -- there is no good candidate still present for parent gene to all these copies. These results are summarized in the table below:

The role of CpG mutations
Human PRDM9 has 39 CpG sites in its coding exons, potentially mutational hotspots. After attempted dna repair, these usually resolve to CpA or TpG. If not at a synonymous site, these changes alter the encoded amino acid. Some 28 of the CpG sites are at arginine CGn codons (of which the protein has 90 overall). These always result in a substitution: for G -> A, histidine for CGT and CGC and glutamine for CGG and CGA; for C -> T, cysteine for CGT and CGC and tryptophan and stop codon for CGG and CGA. These changes are in fact seen in many of the reference sequences. The display below shows wildtype human PRDM9 in the top lines and the effects of G -> A and C -> T in the next. The zinc finger array is highlighted. Note that position -1 is sensitive to the CpG hotspot effect, at least in human PRDM9 as it stands. However the rapid evolution reported for the four dna-recognizing residues cannot be primarily attributed to the CpG effect. The terminal partial finger YVCREDE* is commonly altered to Y*CREDE* but this is likely insufficient for loss of function.

Excluding pseudogenes, a weblogo from an alignment of the remaining placental PRDM7 and PRDM9 genes illustrates the location of potential CpG mutations relative to conserved residues. These will be relatively high frequency disease alleles. In the initial KRAB domain, the potentially affected arginines are not especially well-conserved. However, at the first site, neither histidine nor cysteine is part of the reduced alphabet ans so these changes are unlikely to be tolerated. At the second and third sites, glutamine does occur secondarily in some species (cow, sheep and muntjac) and murid rodents, respectively. These changes are thus borderline for adverse effects on functionality.
In terms of potentially protective upstream CpG islands, PRDM9 has none. Three occur somewhat near the start of PRDM7 but do not extend into the coding region and may not be associated at all with this gene. Thus cytidines would be methylated in both coding regions, rendering them susceptible to hotspot mutations. The composite snapshot below from the UCSC human genome browser shows CpG islands relative to the two genes.
Structural considerations in C2H2 zinc fingers
High resolution structures of C2H2 zinc finger domains have been available for decades. As the name suggests, the divalent zinc atom locks the two cysteines and two histidines into a rigid geometry providing a core conformation that a small peptide of 28 residues could not otherwise stably assume. Note in the unbound state, finger tips must retain flexibility while the domain ensemble scans its genome for specific dna sequences appropriate to its function. Each finger binds a trinucleotide -- in effect making a zinc finger the protein counterpart to tRNA anticodon. However overall binding is not a simple read-off code because adjacent fingers alter each other's specificities in subtle ways.
The linker region TGEKP plays a key role when the correct DNA sequence is encountered, snap-locking its finger down onto its target by capping the C-terminus of its alpha helix. A hydrogen bond between the first threonine and middle glutamate is key to this binding-induced conformational shift. From comparative genomics, it appears that a serine in first position can also form this hydrogen bond. The role of the glycine is to stay out of the way; the lysine counterbalances the negative charge of the glutamate; the proline terminates any helical propensity, allowing a fresh start in the adjacent finger.
While this motif is immensely conserved within C2H2 zinc finger of PDRM9 homologs, exceptions do occur. It is important to understand these because these loss of dna lock-down could loosen or even eliminate trinucleotide binding specificity. Such steps might represent initial stages of pseudogenization. However many exceptions occur within the first or last fingers. It is also common for fragmentary and imperfect motifs to end the protein, sometimes continuing on in another reading frame past the current stop codon.
Note in aligning zinc finger motifs, the breaks should always be put at the end of the linker region. It is completely illogical to break at the first cysteine as some authors do because capping by the linker region is specific to its zinc finger, not the following one.
Predicting dna binding sites of zinc finger domains
The zinc knuckle preceding the PR (SET) domain
A 2011 crystallographic study establishes that a short motif YC..C..........C..HGP found in 6 members of the human PRDM gene family binds zinc via the 3 cysteines and a histidine. The fold most closely resembles the previously known RanBP2 zinc finger domain which occurs in some 21 human proteins, notably nucleoporins NUP153, NUP358, NPL4, EWS, TLS, RBP56, RBM5, RBM10, TEX13A, RANDB2 and ZRANB2. Not all these domains are necessarily homologous because the fold is small and zinc fingers seem to have evolved numerous times. Such fingers can bind other proteins, ssRNA and likely DNA. Their function in PRDM genes is completely unknown but the aromatic residue preceding the first cysteine may contribute to a pi-bonding base stack with guanines.
The domain begins at a phase 2 exon, meaning that the first codon letter is borrowed from the preceding exon splice donor. A dozen earlier residues from this exon are also used but do not exhibit any conservation outside their orthology class. In most cases the knuckle domain exon also contains a downstream PR(SET) domain but at variable intervening lengths (distances shown are to conserved FGP in center of PR(SET) domain. The function of these intervening residues are unknown.

Structural alignment of all PRDM proteins
To determine the evolutionary relationship of the 16 human PRDM genes, it is useful (given the great divergence in primary sequence) to consider rare genomic events such as intron gain/loss and indels. Only 7 of the 16 contain the knuckle region. Of these PDRM11 is the most closely related to PRMD9. This is fortunate because the 3D structure of PRDM11 was recently determined (PDB: 3RAY) from before the knuckle region on into the final exon, thus allowing threading of PRDM9 (whose structure has not been studied). The dozen-odd conserved patches in these widely diverged paralogs find their explanation in the atomic details of this structure.
The knuckle region apparently represents a one-time domain aquisition relative to a knuckle-less ancestral state. The date of this event relative to species phylogeny and the source of the domain are unclear (it is very unlikely to have evolved in situ). Similarly, the internal phase 00 intron is ancestral even though it breaks up a coherent structural domain. Note the final 12 intron is also ancestral -- the PR(SET) domain never occurs without it even though zinc fingers are not always found in the next exon. However the later 21 intron is a newer acquired feature specific to PRDM9 and its closest associates, post-dating aquisition of the knuckle domain and pre-dating duplication and divergence of the PRDM7/9 group. This again follows from gene tree and parsimony considerations.

The sequences above can be restricted to just alignable residues of the knuckle-containing PRDM, which allows idiosyncratic insertions to be removed. In turn, this removes a great deal of noise in terms of using the data to determine a gene tree. The second set of sequences provides a similarly trimmed and edited set of sequences for the full set of PRDM.

Curated reference sequences
The sequences below have largely been compiled from genome projects -- only rarely do validating transcripts exist at GenBank. Sequences with a single frameshift or other glitch have been edited to allow full length proteins on the theory that the error either reflects an aberrant atypical individual chosen for sequencing or sequencing error in low coverage projects within a difficult region. However such sequences may instead reflect early stages of pseudogenization. Other sequences are in fact clearly pseudogenes; here recognizable exons have been collected to allow rough dating of loss of function.
In the case of more intensively studied species such as human, the number of C2H2 repeats varies widely. Only the reference sequence representative is shown here. This variation likely occurs in all species with the individual animal chosen for sequencing not necessarily the most common allele. Many clades have independent histories of gene amplification and gene loss, making both orthologous and functional comparisons problematic at substantial divergences.
The reference sequences below are also available as here as tab-delimited pdf text that will paste cleanly into rows and columns of a spreadsheet which allows sorting to conveniently select data subsets.
Other useful sequences such as PRDM11, PRDM4 and zinc finger semi-homologs having similar exon and domain structures, are provide in the subsequent section along with syntenic markers such as GAS8.

Tracing the early history of individual exons and concatenations
It is instructive to consider certain closely related placental KRAB, ZNF and PRDM genes that may have some connection to the origin of PRDM7 and PRDM9. Nomenclature is very unsatisfactory in these gene families, as can be seen from lack of correspondence between gene name and intronation which is exceedingly well conserved in metazoa. For example, HKR1 a conventional ZNF family member, is egregiously misnamed. The methylase component is exceedingly old with clear antecedents in bacteria. Evidently gene duplications in an early intronless stem eukaryote were subsequently intronated randomly in different paralogs and shuffled into various larger proteins. Within PRDM*, the gene tree is (((PRDM7,PRDM11),(PRDM4,PRDM10)),PRDM6) with others only related by a PR (SET) domain.
