01

Overview

Prostaglandin-endoperoxide synthase 2 (COX-2), also known as cyclooxygenase-2, is an inducible enzyme responsible for the biosynthesis of prostaglandins from arachidonic acid. It plays a key role in inflammation, pain, and fever. Unlike COX-1, COX-2 expression is typically low but can be rapidly induced by inflammatory stimuli. It is a target for NSAIDs, and its overexpression is associated with various diseases, including arthritis, cancer, and neurodegenerative disorders.
