Comments

Comment Type Description
Catalytic Activity Phosphatidylcholine + H(2)O = 1- acylglycerophosphocholine + a carboxylate. {ECO:0000255|PROSITE- ProRule:PRU10035, ECO:0000255|PROSITE-ProRule:PRU10036}.
Cofactor Name=Ca(2+); Xref=ChEBI:CHEBI:29108; Evidence= ; Note=Binds 1 Ca(2+) ion per subunit. ;
Function PA2 catalyzes the calcium-dependent hydrolysis of the 2- acyl groups in 3-sn-phosphoglycerides, this releases glycerophospholipids and arachidonic acid that serve as the precursors of signal molecules.
Ptm Activated by trypsin cleavage in the duodenum. Can also be activated by thrombin or autocatalytically (By similarity)
Similarity Belongs to the phospholipase A2 family
Subcellular Location Secreted. Note=secreted from pancreatic acinar cells in its inactive form
Subunit Monomer or homodimer. The inactive pro-form is a homotrimer (By similarity)
