NCIt definition : Prostaglandin G/H synthase 1 (599 aa, 69 kDa) is encoded by the human PTGS1 gene.
This protein plays a role in vasoconstriction, blood pressure homeostasis and prostaglandin
metabolism.;
NCIt note : COX-1 is known to be present in most tissues as the housekeeper enzyme, maintains
normal gastric mucosa and influences kidney function, while COX-2 is inducible by
inflammation. They share 60% homology. The expression of Cox-1 is induced by cytokines
and mitogens, hence it is likely to play a role in inflammatory diseases such as rheumatoid
arthritis. It contains one EGF-like domain. Both isoforms have the same affinity to
convert arachidonic acid to prostaglandin. COX-1. Both forms of COX proteins are membrane
associated heme proteins containing cyclooxygenase and peroxidase activities. These
enzymes are targets of NSAID (Non steroidal anti-inflammatory drugs) such as aspirin.;
