Summary
The protein encoded by this gene is a secreted enzyme that catalyzes the degradation of platelet-activating factor to biologically inactive products. Defects in this gene are a cause of platelet-activating factor acetylhydrolase deficiency. Two transcript variants encoding the same protein have been found for this gene.[provided by RefSeq, Dec 2009]

Comments

Comment Type Description
Catalytic Activity 1-alkyl-2-acetyl-sn-glycero-3-phosphocholine + H(2)O = 1-alkyl-sn-glycero-3-phosphocholine + acetate.
Disease Asthma (ASTHMA) [MIM
Disease Atopic hypersensitivity (ATOPY) [MIM
Disease Platelet-activating factor acetylhydrolase deficiency (PAFAD) [MIM
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.
Similarity Belongs to the AB hydrolase superfamily. Lipase family.
Subcellular Location Secreted, extracellular space.
Tissue Specificity Plasma.
