Protein

Cytosolic phospholipase A2

Gene

Pla2g4a

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Selectively hydrolyzes arachidonyl phospholipids in the sn-2 position releasing arachidonic acid. Together with its lysophospholipid activity, it is implicated in the initiation of the inflammatory response.

Catalytic activityi

Phosphatidylcholine + H2O = 1-acylglycerophosphocholine + a carboxylate.
2-lysophosphatidylcholine + H2O = glycerophosphocholine + a carboxylate.

Enzyme regulationi

Stimulated by agonists such as ATP, EGF, thrombin and bradykinin as well as by cytosolic Ca2+.
