1-Alkyl-2-acetylglycerophosphocholine Esterase
PAF 2-Acetylhydrolase; PAF 2-Acylhydrolase; PAF Acetylhydrolase II; Platelet-activating Factor Acetylhydrolase IB; 1 Alkyl 2 acetylglycerophosphocholine Esterase; 2-Acetylhydrolase, PAF; Acetylhydrolase II, PAF; Acetylhydrolase, PAF
A lipoprotein-associated PHOSPHOLIPASE A2 which modulates the action of PLATELET ACTIVATING FACTOR by hydrolyzing the SN-2 ester bond to yield the biologically inactive lyso-platelet-activating factor. It has specificity for phospholipid substrates with short-chain residues at the SN-2 position, but inactive against long-chain phospholipids. Deficiency in this enzyme is associated with many diseases including ASTHMA, and HYPERCHOLESTEROLEMIA.
