Summaries for SEPSECS Gene

Entrez Gene Summary for SEPSECS Gene

  • 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]

GeneCards Summary for SEPSECS Gene

SEPSECS (Sep (O-Phosphoserine) TRNA:Sec (Selenocysteine) TRNA Synthase) is a Protein Coding gene. Diseases associated with SEPSECS include pontocerebellar hypoplasia type 2d and acute liver failure. Among its related pathways are PDGFR-beta signaling pathway and Selenium Metabolism and Selenoproteins. GO annotations related to this gene include pyridoxal phosphate binding and transferase activity, transferring selenium-containing groups.
