Protein

Platelet-activating factor acetylhydrolase 2, cytoplasmic

Gene

PAFAH2

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

Functioni

Has a marked selectivity for phospholipids with short acyl chains at the sn-2 position. May share a common physiologic function with the plasma-type enzyme.

Catalytic activityi

1-alkyl-2-acetyl-sn-glycero-3-phosphocholine + H2O = 1-alkyl-sn-glycero-3-phosphocholine + acetate.

Enzyme regulationi

Inhibited by phenylmethanesulfonyl fluoride, 3,4,dichloroisocoumarin, diisopropyl fluorophosphate (DFP) and diethyl p-nitrophenyl phosphate (DENP).
