Prostaglandin G/H Synthase 1 (COX-1)

Target
COX-1
Molecular classification
Enzyme, Cyclooxygenase, Dioxygenase, Peroxidase
01

Overview

Prostaglandin G/H synthase 1 (COX-1) is a key enzyme responsible for the biosynthesis of prostaglandins from arachidonic acid. It is constitutively expressed in most tissues and plays a crucial role in maintaining physiological functions such as gastric mucosal protection, regulation of blood flow, platelet aggregation, and kidney function. Inhibition of COX-1 by NSAIDs can lead to adverse effects such as gastrointestinal ulceration.
