Summaries for GSTO1 Gene

Entrez Gene Summary for GSTO1 Gene

  • The protein encoded by this gene is an omega class glutathione S-transferase (GST) with glutathione-dependent thiol transferase and dehydroascorbate reductase activities. GSTs are involved in the metabolism of xenobiotics and carcinogens. The encoded protein acts as a homodimer and is found in the cytoplasm. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2010]

GeneCards Summary for GSTO1 Gene

GSTO1 (Glutathione S-Transferase Omega 1) is a Protein Coding gene. Diseases associated with GSTO1 include cisplatin toxicity and barretts adenocarcinoma. Among its related pathways are Disease and Metabolism. GO annotations related to this gene include oxidoreductase activity and glutathione dehydrogenase (ascorbate) activity. An important paralog of this gene is GSTO2.
