Gene Information

Official Symbol: SEPSECS
Official Name: Sep (O-phosphoserine) tRNA:Sec (selenocysteine) tRNA synthase
Aliases and Previous Symbols: N/A
Entrez ID: 51091
UniProt: Q9HD40
Interactions: BioGRID

Function Summary

Entrez Summary: The amino acid selenocysteine is the only amino acid that does not have its own tRNA synthetase. Instead, this amino acid is synthesized on its cognate tRNA in a three step process. The protein encoded by this gene catalyzes the third step in the process, the conversion of O-phosphoseryl-tRNA(Sec) to selenocysteinyl-tRNA(Sec).[provided by RefSeq, Mar 2011].
UniProt Summary: Converts O-phosphoseryl-tRNA(Sec) to selenocysteinyl- tRNA(Sec) required for selenoprotein biosynthesis. {ECO:0000269|PubMed:17142313}.
