Biochem/physiol Actions

COX-I, an isoform of COX enzyme with 599 amino acid residues, catalyzes the conversion of arachinodate to prostaglandin H2. It is expressed mainly in the gut for the production of prostaglandins, which inhibit gastric secretion. It is involved in the regulation of homeostatic functions throughout the body, such as vascular hemostasis, renal blood flow, and maintenance of glomerular function. It is a target of NSAID (non-steroidal anti-inflammatory drugs) such as aspirin. COX-I can be induced by IL-β and other cytokines in monocytes, macrophages, and other cells as part of the inflammatory response.
