Summaries for KYAT1 Gene

Entrez Gene Summary for KYAT1 Gene

  • This gene encodes a cytosolic enzyme that is responsible for the metabolism of cysteine conjugates of certain halogenated alkenes and alkanes. This metabolism can form reactive metabolites leading to nephrotoxicity and neurotoxicity. Increased levels of this enzyme have been linked to schizophrenia. Multiple transcript variants that encode different isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for KYAT1 Gene

KYAT1 (Kynurenine Aminotransferase 1) is a Protein Coding gene. Diseases associated with KYAT1 include schizophrenia. Among its related pathways are Metabolism and Histidine, lysine, phenylalanine, tyrosine, proline and tryptophan catabolism. An important paralog of this gene is TAT.

UniProtKB/Swiss-Prot for KYAT1 Gene

  • Catalyzes the irreversible transamination of the L-tryptophan metabolite L-kynurenine to form kynurenic acid (KA). Metabolizes the cysteine conjugates of certain halogenated alkenes and alkanes to form reactive metabolites. Catalyzes the beta-elimination of S-conjugates and Se-conjugates of L-(seleno)cysteine, resulting in the cleavage of the C-S or C-Se bond.
