| | | Concise_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. |
