Selenoprotein evolution: introduction
Introduction to selenoprotein evolution
(other selenoproteins shortly)
Selenoprotein SELU: 3 paralogs, variable timing losses
SELU: This family consists of three deeply diverged (distinct exon patterns) paralogs. The encoding gene has 5 average exons with anomalously short introns like many selenoproteins. In the SELU1 group, selenocysteine occurs in a UxxC motif already in the earliest deuterostome but drops out in mammals after monotremes, being replaced by CxxC in marsupials and placentals. Amphibia separately lost selenocysteine.
The second paralog SELU2 has selenocysteine in bilaterans only to the node of sea urchin, suggesting it was lost early in the deuterostome ancestor. It is the closer paralog of SelU1, 36% vs 27% percent identity. No vestigal SECIS element persists in living species that encode cysteine. (The decayed SECIS elements still identifiable in 3' UTR of cysteine-containing GPX6 genes in rodents and human GPX5 represent much more recent loss of selenocysteine.)
The third paralog SELU3 has cysteine in all species for which a sequence is available. It might be called virtual selenoprotein supposing orthologs in early diverging eukaryotes could be located that contained selenocysteine. This would suggest a scenario in which selenocysteine was present in an ancestral gene prior to gene duplications followed by conversion to cysteine in different phylogenetic patterns within each gene subfamily.
This family exhibits the "selenocysteine rachet": if selenocysteine happens to be replaced by ordinary cysteine (despite catalytic inferiority) in some stem lineage, the unselected 3' UTR SECIS element then deteriorates over a few million years from accrued mutations, for the same reason (lack of purifying selection) the crayfish in the cave loses its imaging opsins. Consequently the whole following clade will contain cysteine -- a reversion to TGA at the cystein codon might occur but it would simultaneously require a multi-step reversion or de novo evolution of a SECIS element, ie all SECIS elements are ancient and selenocysteines cannot wink back on paraphyletically. (However the overall selenoproteome can still increase over time because of gene duplications elsewhere.)

Selenoprotein SEPW1: small protein with an odd paralog
Selenoprotein SEPW1 is one of the shortest known mammalian proteins at 87 aa. With its CxxU motif, it is likely limited to simple redox reactions. Curiously, despite the small size protein still has 5 coding exons. One of these is of relatively recent origin because chondrichtyes and telost fish have the second and third exons fused (which, given the tree and extreme rarity of intron gain/loss must be the ancestral condition.
