Comments

FUNCTION: PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. Inhibits collagen-induced platelet aggregation (By similarity).
CATALYTIC ACTIVITY: Phosphatidylcholine + H₂O = 1-acylglycerophosphocholine + a carboxylate.
COFACTOR: Calcium (Probable).
SUBCELLULAR LOCATION: Secreted (By similarity).
TISSUE SPECIFICITY: Expressed by the venom gland.
SIMILARITY: Belongs to the phospholipase A2 family. Group I subfamily.
