catalytic activity:Phosphatidylcholine + H(2)O = 1-acylglycerophosphocholine + a carboxylate.,cofactor:Binds 1 calcium ion per subunit.,function:PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. Has a preference for arachidonic-containing phospholipids.,similarity:Belongs to the phospholipase A2 family.,tissue specificity:Restricted to the brain, heart, lung, and placenta.,
Secreted . Cytoplasm . Through binding to heparan sulfate proteoglycan, may be localized to cytoplasmic compartments enriched in anionic phospholipids. .
Restricted to the brain, heart, lung, and placenta.
