PLA2G4A (Cytosolic Phospholipase A2, cPLA2, Phospholipase A2 Group IVA, Phospholipase A2, Phosphatidylcholine 2-acylhydrolase, Lysophospholipase, PLA2G4, CPLA2)
Description:
PLA2G4A is a member of the cytosolic phospholipase A2 group IV family. The enzyme catalyzes the hydrolysis of membrane phospholipids to release arachidonic acid which is subsequently metabolized into eicosanoids. Eicosanoids, including prostaglandins and leukotrienes, are lipid-based cellular hormones that regulate hemodynamics, inflammatory responses, and other intracellular pathways. The hydrolysis reaction also produces lysophospholipids that are converted into platelet-activating factor. The enzyme is activated by increased intracellular Ca(2+) levels and phosphorylation, resulting in its translocation from the cytosol and nucleus to perinuclear membrane vesicles.

Applications:
Suitable for use in ELISA and Western Blot. Other applications not tested.

Recommended Dilution:
ELISA: 1:32,000
Western Blot: 1-3ug/ml, observed in lysates of cell lines HeLa and NIH3T3 on ~90kD bands
Optimal dilutions to be determined by the researcher.
