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) |
