Anti-KYAT3 antibodies are used in the immunodetection of the protein kynurenine aminotransferase 3. In humans, the canonical protein has a reported length of 454 amino acid residues and a mass of 51.4 kDa. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Class-I pyridoxal-phosphate-dependent aminotransferase protein family, KYAT3 is known to catalyze the irreversible transamination of the L-tryptophan metabolite L-kynurenine to form kynurenic acid (KA), an intermediate in the tryptophan catabolic pathway which is also a broad spectrum antagonist of the three ionotropic excitatory amino acid receptors among others. Synonyms for this target antigen include cysteine-S-conjugate beta-lyase 2, kynurenine aminotransferase III, kynurenine--glyoxylate transaminase, kynurenine--oxoglutarate transaminase III, and kynurenine--oxoglutarate transaminase 3. KYAT3 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Western Blot is the most common application for the KYAT3 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
