Introduction to selenocysteine insertion into selenoproteins

The SECIS element in 3' UTR of selenoproteins allows the insertion of selenocysteine for the appropriate TGA codon at time of translation. Auxillary gene products are needed for this to happen, including a selenocysteine-specific translation elongation factor (eEFSec), Sec-tRNA[Ser]Sec, ribosomal protein L30, and a binding protein (SBP2).

The SBP2 protein has three domains, including a conserved L7Ae RNA binding motif for SECIS RNA binding, a not completely overlapping ribosome binding site and a redox-sensitive cysteine-rich domain. SBP2 shuttles between the nucleus and the cytoplasm via nuclear localization motif SELEQNESSKKNKKKKEKSKSSYEVLPVQE and nuclear export signal motifs, the latter using the CRM1 pathway.


The kink-turn tertiary structure in the SECIS element is at the core of binding recognition. A mutation in that of SEPN or in SB2 lead to rigid spine muscular dystrophy or abnormal thyroid hormone function, the latter through inadequate production of DIO2 needed to activate thyroid hormone T4.

A strong paralog of BP2 was noticed and briely studied earlier. That protein, KIAA0256, also has 17 coding exons with near-identical intron locations and phases and full-length alignability, establishing KIAA0256 and BP2 as resulting from an ancestral gene duplication. The percent identity overall is only 42% but reaches 72% (human to human) in the 3 exons defining the L7Ae kink-turn binding motif.

Since both genes can be recovered from chondrichthyes, lamprey, and amphioxus, the duplication event preceded the emergence of chordates. The roots of the selenoproteome and the insertion mechanism lie much deeper in pre-metazoa so it follows that the parent gene must have assumed the key SECIS recognition roles (as did both descendent genes, at least initially).

We could ask if KIAA0256 still plays a role in SECIS in contemporary organisms. One possibility is that some of the 30-odd selenoproteins preferentially use KIAA0256 over BP2, correlating to the two observed structural classes of SECIS elements (which needs to be revisited in the genomics era). Another possibility is differential use during development or in various cell types. It's worth noting that KIAA0256 is considerably more conserved across its length than BP2, which has only a few exons conserved back to fish) suggesting the latter has a more limited role.

A literature review establishes that DIO, GPX, and SEPP1 were generally taken as proxies for all selenoprotein SECIS elements in terms of establishing a role for BP2. Yet the timing of expansion of these and specialization of the former to thyroid during the period of gene duplication may have tainted their representativeness. Possibly many other selenoproteins utilize KIAA0256 at least to some extent. That would account for the greater conservation of KIAA0256 and the difficulty finding SECIS elements in expected position for certain selenoproteins, ie their elements may be adapted to a different receptor and so have low Cove scores to the extent that tool is based on the BP2 fold paradigm.

Ribosomal protein L30 appears also to bind the SECIS kink-turn and play a role in selenocysteine insertion despite its meagre length of 114 amino acids. Likely many ribosomal proteins, L30 has remarkable sequence conservation, here still 94% at human-lamprey.

L30 has weak homology and secondary structure parallels to the pertinent region of BP2 and KIAA0256. These latter proteins might be viewed as domain composites that have accreted the kink-turn binding domain long ago from this undoubtedly ancient ribosomal protein. This opens a window on the origin of selenocysteine insertion in early eukaryotes.

Note: the Irish proband with K438stop/IVS8ds+29G/A involving a new splice donor mutation leading to early truncation has been incorrectly described as a SECISBP2 knockout; in fact 48% production of wildtype maternal allele still occurs. Additionally, KIAA0256 may be able to partially compensate for reduction in level or loss of SECISBP2. Knockout mice for tRNA(Sec), unable to make any selenoproteins, die in utero.

These same authors, in Figure 1B published twice identically among rare papers to ever consider KIAA0256 aligned full length SECISBP2 to an intermediate region of the KIAA0256 gene that happened to begin with a methionine, namely residues 422-849 of the 1056 residue protein (which includes the motif-bearing residues 632-829 of exons 14-16).

KIAA0256 and SECISBP2 actually align well over their entire lengths and have 17 exactly comparable exons. There is no reason to believe that such an odd fragment studied on a few SECIS sequences could accurately represent binding properties of full length protein in regards to the 25-odd orthology class of SECIS elements. However this became accepted folklore with the selenocysteine research community and the properties of full lenth KIAA0256 have never been determined.
