Subcellular location

Subcellular Location:
Secreted, extracellular space.

Function

Function:
Modulates the action of platelet-activating factor (PAF) by hydrolyzing the sn-2 ester bond to yield the biologically inactive lyso-PAF. Has a specificity for substrates with a short residue at the sn-2 position. It is inactive against long-chain phospholipids.
Catalytic Activity:
1-alkyl-2-acetyl-sn-glycero-3-phosphocholine + H(2)O = 1-alkyl-sn-glycero-3-phosphocholine + acetate.
Active Site:
ACT_SITE 273 273 Nucleophile.
