Provisional_description
| C06G3.7 encodes an homolog of the mammalian thioredoxin reductase isozymes TR1 and TR2; like its mammalian homologs, C06G3.7 has a TGA-encoded C-terminal penultimate selenocysteine (Sec) residue; labelling of C. elegans with selenium-75 demonstrates that TR-Se is the major naturally occurring selenoprotein in C. elegans, and computational analysis indicates that it is probably the only selenoprotein encoded by the genome; the 3'-untranslated region of this gene contains a selenocysteine insertion sequence that is functional in mammalian cell culture; by phylogenetic profiling, C06G3.7 protein is predicted to be mitochondrial. |

| | | | The C06G3.7 gene contains a a TGA selenocysteine codon at the same position as its mammalian homolog TTR, and a functional selenocysteine insertion sequence (SECIS) element. |
| | | | The TGA SeCys codon of C06G3.7 is currently treated as an actual stop to the CDS, and there may be other such cases in the genome as well. |
| | | | This gene encodes a protein predicted by Eisenberg and coworkers, with 68% accuracy, to be mitochondrial. |
| | | | Proteins localized to a given organelle by experiments tend to share a characteristic phylogenetic distribution of their homologs, called a phylogenetic profile. |
| | | | For instance, mitochondrial proteins can be identified effectively by their phylogenetic profiles. |
| | | | By applying phylogenetic profile analysis to the C. elegans genome, Eisenberg and coworkers inferred that this gene, along with 2-4% of all the nuclear genes in C. elegans, encodes a mitochondrial protein. |
| | | | The large fraction of organism-specific and eukaryote-derived genes suggests that C. elegans mitochondria perform specialized roles absent from prokaryotic mitochondrial ancestors. |
