Group 3 secretory phospholipase A2 (PLA2G3)

PA2 catalyzes the calcium-dependent hydrolysis of the 2- acyl groups in 3-sn-phosphoglycerides. Shows an 11-fold taste for phosphatidylglycerol over phosphatidylcholine (PC).

Preferential cleavage: 1-palmitoyl-2-linoleoyl- phosphatidylethanolamine (PE) > 1-palmitoyl-2-linoleoyl-PC > 1- palmitoyl-2-arachidonoyl-PC > 1-palmitoyl-2-arachidonoyl-PE. Plays a role in ciliogenesis.
