Biological function summary
COX-1 is involved in producing prostaglandins that regulate a variety of normal physiological processes including gastric mucosal protection renal blood flow and platelet aggregation. Unlike COX-2 COX-1 is not induced by inflammatory stimuli and is not part of an inducible complex. It serves to maintain essential physiological functions in various organs and systems making its activity critical for cellular maintenance.
Pathways
COX-1 is primarily involved in the prostaglandin biosynthesis pathway. It converts arachidonic acid into prostaglandin H2 a precursor for other prostaglandins and thromboxanes. Thromboxane A2 produced from this pathway plays an important role in platelet aggregation and vasoconstriction linking COX-1's functions with hemostatic processes. Another protein involved in this pathway is thromboxane synthase which further processes the products of COX-1 activity.

General info
Function
Dual cyclooxygenase and peroxidase that plays an important role in the biosynthesis pathway of prostanoids, a class of C20 oxylipins mainly derived from arachidonate ((5Z,8Z,11Z,14Z)-eicosatetraenoate, AA, C20 : 4(n-6)), with a particular role in the inflammatory response. The cyclooxygenase activity oxygenates AA to the hydroperoxy endoperoxide prostaglandin G2 (PGG2), and the peroxidase activity reduces PGG2 to the hydroxy endoperoxide prostaglandin H2 (PGH2), the precursor of all 2-series prostaglandins and thromboxanes. This complex transformation is initiated by abstraction of hydrogen at carbon 13 (with S-stereochemistry), followed by insertion of molecular O2 to form the endoperoxide bridge between carbon 9 and 11 that defines prostaglandins. The insertion of a second molecule of O2 (bis-oxygenase activity) yields a hydroperoxy group in PGG2 that is then reduced to PGH2 by two electrons (PubMed : 7947975). Involved in the constitutive production of prostanoids in particular in the stomach and platelets. In gastric epithelial cells, it is a key step in the generation of prostaglandins, such as prostaglandin E2 (PGE2), which plays an important role in cytoprotection. In platelets, it is involved in the generation of thromboxane A2 (TXA2), which promotes platelet activation and aggregation, vasoconstriction and proliferation of vascular smooth muscle cells (Probable). Can also use linoleate (LA, (9Z,12Z)-octadecadienoate, C18 : 2(n-6)) as substrate and produce hydroxyoctadecadienoates (HODEs) in a regio- and stereospecific manner, being (9R)-HODE ((9R)-hydroxy-(10E,12Z)-octadecadienoate) and (13S)-HODE ((13S)-hydroxy-(9Z,11E)-octadecadienoate) its major products (By similarity).
