COX1 IHC Antibody

Description

Cyclooxygenase 1 (COX1), also knows as Prostaglandin-endoperoxide synthase (PTGS1), is the key enzyme in prostaglandin biosynthesis. The gene was approximately 40 kb long, with 11 protein-coding exons. There were 599 amino acid residues with a calculated molecular mass of approximately 68 kD. By analysis of a human/hamster somatic hybrid DNA panel, Funk et al. (1991) demonstrated that the PTGS1 gene maps to chromosome 9.  Human prostaglandin endoperoxide synthase exhibited 91% amino acid identity with the sheep enzyme.Prostaglandin synthase 1 gene disruption in mice reduces arachidonic acid-induced inflammation and indomethacin-induced gastric ulceration.
