Predicted to enable calcium ion binding activity; calcium-dependent phospholipase A2 activity; and phospholipid binding activity. Predicted to be involved in phosphatidylcholine metabolic process and phosphatidylglycerol metabolic process. Predicted to act upstream of or within arachidonate secretion; lipid catabolic process; and phospholipid metabolic process. Predicted to be located in extracellular region. Orthologous to human PLA2G1B (phospholipase A2 group IB).
