SECIS binding proteins: KIAA0256 and SBP2

KIAA0256: mis-annotated and forgotten ancestral SECIS binding protein

KIAA0256 originally arose in a GenBank submission package from a large-scale mRNA sequencing project at the Kaluza Institute. While high quality, it skips over a highly conserved exon 8. This does not alter downstream reading frame since the skipped exon resides in a series of consecutive phase 00 splices. NCBI staff then confounded the record by posting experimentally unsupported gene predictions -- all exon-skipping -- from various genome assemblies lacking significant transcript programs mis-labelling them as mRNAs, thus entrenching the incomplete variant as normal form.

Two subsequent papers featuring the twice-published Figure 1B aligned full length SBP2 to an intermediate region of the exon-skipping gene model of KIAA0256 that by coincidence began with a methionine, namely residues 422-849 of the 1101 residue protein which did include the motif-bearing residues 632-829 of exons 14-16. Making matters worse, KIAA0256 contains an additional immensely conserved exon 11 that lacks a detectable counterpart in SBP2. SwissProt provides the proper full length protein Q93073 without a supporting accession.

The effect of these early errors meant early SECIS binding experiments used KIAA0256 protein lacking the conserved exon 8, this variant lacked relevent SECIS binding properties, whick lead to abandonment of further experimentation. Consequently we know nothing about the SECIS binding properties of full length KIAA0256 protein.

There is no reason to believe an odd fragment studied on a small subset of SECIS elements could accurately reflect binding properties of full length protein in regards to all 25 orthology classes of human SECIS elements. However these results remain accepted folklore within the selenocysteine research community even today.

An Irish family with an SBP2 compound mutation (paternal allele inactive, maternal allele a splice donor mutation leading to early truncation: K438stop/IVS8ds+29G/A ) has been incorrectly described by these same authors as a SBP2 knockout; in fact 48% production of wildtype maternal allele still occurs. In addition, 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.

While baboon also has experimental transcripts skipping this exon (FC145891, FC178616), mammalian transcripts almost always retain the exon, for example human (AK307480 but not BF055173, CN482709, BE930773, DW431473), macaque (CJ457866), mouse (AK145135), rat (CK602552), dog (CO708934), horse (CX604216), cow (CK846448), sheep (EE864720), and even chicken (DR417186), frogs, and fish. Thus inclusion of exon 8 is the ancestral state. Skipping is documented to date only in these two primates.

Transcriptional processing in mammals is error-rich, producing numerous defective mRNA variants that never amount to useful regulation or stable protein -- downstream quality controls quickly eliminate them. While exon-skipping in some cases may have adaptive significance, without significant comparative genomics support, the default hypothesis is they do not. Here it is difficult to distinguish between a weakened exon 8 splice acceptor in apes leading to a fraction of defective transcripts versus an innovative functional truncated form. These alternatives might be resolvable from 3D structural considerations -- deleting 45 conserved residues in an ancient exon is highly problematic.

However within this same protein, the apparent ancestral loss of exon 11 in SBP2 provides proof that exon-skipping can be evolutionarily fixed. That extraordinary event (which occured prior to chondrichthyes divergence: ES788504) certainly differentiated SBP2 from KIAA0256. Exon 11 is in the 99th percentile of vertebrate exon conservation, being 100% conserved back to amniotes (though divergence is high in early deuterostomes, below). It did not arise as exon gain from retroposon co-optation. This surely implies a critical role in KIAA0256 lost in SBP2.

KIAA0256 and SECISBP2 actually align moderately well over their entire lengths and have 17 perfectly comparable exons (trillion:1 odds for coincidence), meaning they reflect a segmental gene duplication. It is imperative to enforce exon boundaries to achieve true homological alignment of two proteins this diverged and so gappy N-terminally; structure-based alignment has different rules (allowing convergent evolution) and different goals.

The teleost fish Pimephales promelas has sufficient transcript coverage to allow recover of an accurate nearly full length KIAA0256 gene with a respectable 62% identity to human. (No fish has sufficient transcripts to recover full length SBP2.) That gene is shown below as homologically gapped exon-by-exon to human. Some early exons are quite well conserved over many billions of years of branch length, strong evidence that they retain an unknown function under strong selection. However the gaps in other early exons are incompatible with retention of tertiary protein structure. No early pfam domain can be found.

We have to wonder how sea urchin, which has a full length apparent ortholog of KIAA0256 on Scaffold18963:101,648-115,302 but nothing clustering to SECISBP2, can insert selenocysteine into its numerous selenoproteins (SEPHS1, SELU1, SELU2, SELM, SELO, SELW, SELN1, GPX3, GPX2, GPX4, GPX7,...). Unless a second copy has been lost, all SECIS interaction at the ribosome at sea urchin divergence appears to have been handled by KIAA056.

The same can be asked for amphioxus and tunicate. These species too have numerous selenoproteins yet their genome assemblies contain but a single homologous gene with vastly higher homology to KIAA0256. Lamprey genome lacks coverage. It's difficult to extend orthologous annotation into protostomes and cnidaria because divergence is high even within the L7ae region.

Using the kink-turn binding motifs of the two human proteins in turn as blastp query against the both collections of deuterostome KIAA0256 and SECISBP2 sequences, establishes KIAA0256 as the slower evolving protein by a wide margin. This fits KIAA0256 retaining ancestral function and its gene duplicate SECISBP2 specializing via a neofunctionalization.

Both proteins bristle with potential NxT/S glycosylation sites, 13 for KIAA0256 and 6 for SECISBP2, with implications for cellular localization. These do not lie in homologous positions, unsurprisingly in view of the deep divergence of these genes and volatility of glycosylation sites in other gene families. These sites are conserved only to moderate depth -- and that could be for reasons unrelated to glycosylation). Hence glycosylation site do not provide reliable anchors in region of poor sequence conservation. SwissProt predicts phosphoserine sites in exon 5 (of unknown functionality); those too have only moderate phylogenetic conservation.

Reference set of metazoan KIAA0256 full length sequences

It is very difficult to extract full length genes from phylogenetically representative organisms in the case of KIAA0256. That's because the gene is twice average size (thus seldom tiled completely by transcripts), has two very short exons that do not emerge from alignment methods, several consecutive poorly conserved exons rife with indels, and a run-on carboxy terminus. Nearly every pipeline entry in GenBank non-redundant contains gross errors, including long internal repeats and severely truncated genes.

It will prove imperative to initiate massive cDNA programs in non-teleost species for this (and many other anomalous genes) for which homological modelling will never work. Tiled coverage will be necessary, not merely end-sequencing.

Why would a gene seemingly essential to making numerous essential selenoproteins evolve so erratically? The ribosome and SECIS elements with which it interacts are exceedingly conserved and its role must have been stable for over half a billion years. KIAA0256 has a dumbbell conservation structure, possibly suggesting a fusion of two proteins. Only the amino terminal region of the upstream partner was conserved, along with the SECIS and L7Ae motif of the downstream partner, with little selection on the run-on carboxy terminal tail (not uncommon in proeins).
