CC   -!- FUNCTION: Secretory calcium-dependent phospholipase A2 that primarily
CC       targets dietary phospholipids in the intestinal tract
CC       (PubMed:17603006). Hydrolyzes the ester bond of the fatty acyl group
CC       attached at sn-2 position of phospholipids (phospholipase A2 activity)
CC       with preference for phosphatidylethanolamines and phosphatidylglycerols
CC       over phosphatidylcholines (By similarity). May play a role in the
CC       biosynthesis of N-acyl ethanolamines that regulate energy metabolism
CC       and inflammation in the intestinal tract. Hydrolyzes N-acyl
CC       phosphatidylethanolamines to N-acyl lysophosphatidylethanolamines,
CC       which are further cleaved by a lysophospholipase D to release N-acyl
CC       ethanolamines (By similarity). May act in an autocrine and paracrine
CC       manner (By similarity). Has anti-helminth activity in a process
CC       regulated by gut microbiota. Upon helminth infection of intestinal
CC       epithelia, directly affects phosphatidylethanolamine contents in the
CC       membrane of helminth larvae, likely controlling an array of
CC       phospholipid-mediated cellular processes such as membrane fusion and
CC       cell division while providing for better immune recognition, ultimately
CC       reducing larvae integrity and infectivity (By similarity).
