Background

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.

FAQs for PLA2G4A Antibody (AF6659). (Showing 1 - 1 of 1 FAQ).

  1. Hi. Actually I want to purchase anti cPLA2 antibody raised in rabbit which can bind to both phorphorylated and unphosphorylated mouse cPLA2 group IV. I want to a gel shift assay with western blotting to show that my protein of interest is causing the phosphorylation of cPLA2 inside the mouse macrophages RAW cells.Can you please tell me which antibody would be suitable for the purpose. Thanks a lot.
    • Here are our antibodies raised in rabbit that have been validated to detect cPLA2 in mouse samples in a western blot. We have not specifically confirmed the ability of these antibodies to detect both the phosphorylated and unphosphorylated forms of the protein, and I cannot guarantee that they will clearly differentiate between the two.

Effects of SDF-1-CXCR4/CXCR7 pathway on MSC chemotaxis in vitro.(A) The chemotaxis in response to SDF-1 alpha (10 ng/ml for 12 h) was performed in the NP-MSCs and HP-MSCs treated with a neutralizing anti-CXCR4 antibody, an anti-CXCR7 antibody, and the respective isotype-matched control antibodies. *P<0.05, vs NP-MSCs; †P<0.05, vs the respective isotype-matched control antibodies. (B) NP-MSCs were transiently overexpressed with CXCR4 using pORF9-mCXCR4 vector or with CXCR7 using pORF9-mCXCR7 vector (n = 6). A negative control empty (pORF9-MCS) vector was used. (C) The transfected cells were subjected to chemotaxis in response to the indicated concentrations of SDF-1 alpha for 12 h. *P<0.05, vs the empty vector. (D and E) Western blot analysis (D) and FCM (E) were performed to determine the intracellular and extracellular expression of both CXCR4 and CXCR7 in the cells treated with or without SDF-1 alpha (50 ng/ml for 60 min).
