Protein

Cytosolic phospholipase A2 delta

Gene

PLA2G4D

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at transcript leveli

Functioni

Calcium-dependent phospholipase A2 that selectively hydrolyzes glycerophospholipids in the sn-2 position. Not arachidonic acid-specific but has linoleic acid-specific activity. May play a role in inflammation in psoriatic lesions.1 Publication

Catalytic activityi

Phosphatidylcholine + H2O = 1-acylglycerophosphocholine + a carboxylate.

Enzyme regulationi

Stimulated by cytosolic Ca2+.1 Publication
