UniProt Protein Function: | KMO: Catalyzes the hydroxylation of L-kynurenine (L-Kyn) to form 3-hydroxy-L-kynurenine (L-3OHKyn). Required for synthesis of quinolinic acid, a neurotoxic NMDA receptor antagonist and potential endogenous inhibitor of NMDA receptor signaling in axonal targeting, synaptogenesis and apoptosis during brain development. Quinolinic acid may also affect NMDA receptor signaling in pancreatic beta cells, osteoblasts, myocardial cells, and the gastrointestinal tract. Belongs to the aromatic-ring hydroxylase family. KMO subfamily. 3 isoforms of the human protein are produced by alternative splicing.Protein type: Oxidoreductase; Membrane protein, integral; Amino Acid Metabolism - tryptophan; Mitochondrial; EC 1.14.13.9; Membrane protein, multi-passChromosomal Location of Human Ortholog: 1q42-q44Cellular Component: cytosol; mitochondrial outer membraneMolecular Function: FAD binding; kynurenine 3-monooxygenase activity; NAD(P)H oxidase activityBiological Process: NAD metabolic process; response to salt stress; tryptophan catabolic process |
