Anti-KYAT1 antibodies are used in the immunodetection of the protein kynurenine aminotransferase 1. In humans, the canonical protein has a reported length of 422 amino acid residues and a mass of 47.9 kDa. Its subcellular localization is in the cytoplasm. 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, KYAT1 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 GTK, KATI, kynurenine--oxoglutarate transaminase 1, beta-lysase, kidney, and CCBL1. Some KYAT1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
