Preparation and Storage

Background: PLA2G4A

PLA2G4A (Phospholipase A2 Group IVA; also cytosolic phospholipase A2 alpha/cPLA2 alpha and lysophospholipase) is an 100-110 kDa member of the cytosolic PLA2 family of enzymes. Expression can be induced in select cell types, including endothelium, smooth muscle, macrophages, PMNs, fibroblasts, mast cells and platelets. Tumor cells often serve as sources for cPLA2 alpha activity. cPLA2 alpha is synthesized in the cytosol where, upon activation, it translocates to sites containing cell membranes, including the Golgi, ER and nuclear membrane. This translocation allows for enzymatic action on membrane phospholipids, generating free arachidonic acid that is converted into proinflammatory eicosanoids. Human cPLA2 alpha is 749 amino acids (aa) in length. It contains a phospholipid-binding and membrane-association C2 domain (aa 1-178), and an overlapping PLA2c domain that demonstrates catalytic activity (aa 140-740). While phosphorylation on Ser505 and Ser727 contribute to activation, there are at least five other utilized phosphorylation sites on the molecule. Phosphorylation may increase the MW of cPLA2 alpha in SDS-Page to about 100 kDa. Full-length (aa 1-749) human PLA2G4A/cPLA2 alpha shares 94% aa sequence identity with mouse PLA2G4A.
