General annotation (Comments)

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

Subcellular location

Secretedextracellular space.

Tissue specificity

Plasma.

Sequence similarities

Belongs to the AB hydrolase superfamily. Lipase family.
