Secretory Phospholipase A2 (sPLA2)

Target
sPLA2
Molecular classification
Enzyme, Phospholipase
01

Overview

Secretory phospholipase A2 (sPLA2) is an enzyme that catalyzes the hydrolysis of the sn-2 ester bond in glycerophospholipids, releasing free fatty acids and lysophospholipids. It plays a crucial role in various biological processes, including inflammation, host immunity, and lipid signaling. Dysregulation of sPLA2 is linked to inflammatory diseases.
