General info

Function

Secretory calcium-dependent phospholipase A2 that primarily targets dietary phospholipids in the intestinal tract (By similarity). Hydrolyzes the ester bond of the fatty acyl group attached at sn-2 position of phospholipids (phospholipase A2 activity) with preference for phosphatidylethanolamines and phosphatidylglycerols over phosphatidylcholines (By similarity). May play a role in the biosynthesis of N-acyl ethanolamines that regulate energy metabolism and inflammation in the intestinal tract. Hydrolyzes N-acyl phosphatidylethanolamines to N-acyl lysophosphatidylethanolamines, which are further cleaved by a lysophospholipase D to release N-acyl ethanolamines (By similarity). May act in an autocrine and paracrine manner (PubMed : 10066760). Upon binding to the PLA2R1 receptor can regulate podocyte survival and glomerular homeostasis (By similarity). Has anti-helminth activity in a process regulated by gut microbiota (PubMed : 29024642). Upon helminth infection of intestinal epithelia, directly affects phosphatidylethanolamine contents in the membrane of helminth larvae, likely controlling an array of phospholipid-mediated cellular processes such as membrane fusion and cell division while providing for better immune recognition, ultimately reducing larvae integrity and infectivity (PubMed : 29024642).

Sequence similarities

Belongs to the phospholipase A2 family.

Post-translational modifications

Activated by trypsin cleavage in the duodenum. Can also be activated by thrombin or autocatalytically.
