Summary
Proteins belonging to the phospholipase A2 (PLA2) family hydrolyze phospholipids into sn2 fatty acids and lysophospholipids. They function in a variety of cellular processes, including the digestion of phospholipids and the production of molecules that induce inflammatory responses. This gene encodes a member of the group II class of secretory PLA2s. The secreted enzyme binds to heparin on the cell surface. Mutations in this gene increase the occurrence of intestinal polyps caused by a dominant mutation in the adenomatosis polyposis coli gene. A frameshift inactivates this gene product in some mouse strains including the strain of the reference genome, C57BL/6J, whereas a functional protein is produced in other strains.

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={ECO:0000250}; Note=Binds 1 Ca(2+) ion per subunit. {ECO:0000250}; |
Function | May play a role in cell proliferation, by increasing the binding of EGF to the cells and thereby modulating its action. In doing so, this isozyme binds to a membrane-associated receptor distinct from the EGF receptor and which could be a heparan- sulfate proteoglycan located on the cell membrane. |
Function | PA2 catalyzes the calcium-dependent hydrolysis of the 2- acyl groups in 3-sn-phosphoglycerides. |
Polymorphism | In strains 129/Sv, B10.RIII and C57BL/6, a polymorphism causes a frameshift and premature truncation of the protein, rendering it inactive. Strains BALB/c, C3H/He, DBA/1, DBA/2, MRL and NZB/B1N contain the normal protein while strain CD- 1 is heterozygous for the mutation. |
Sequence Caution | Sequence=AAB06315.1; Type=Erroneous initiation; Evidence={ECO:0000305}; |
Similarity | Belongs to the phospholipase A2 family. {ECO:0000305}. |
Subcellular Location | Membrane; Peripheral membrane protein. |
Tissue Specificity | Mainly in the Paneth cells adjacent to the stem population in the small intestines. Also expressed in regenerating liver and hyperplastic esophageal epithelium. |
