Synthetic phosphopeptide corresponding to residues surrounding Ser505 of human cPLA2.
Cytosolic phospholipase A2 (cPLA2) is a ubiquitously distributed enzyme that catalyzes the hydrolysis of the sn-2 acyl bond of glycerolipids to produce lysophospholipids and the release of arachidonic acid. cPLA2 has been implicated in diverse cellular responses such as mitogenesis, differentiation, inflammation and cytotoxicity. Calcium binding to the Nterminal CalB domain of cPLA2 promotes the translocation of cPLA2 from cytosol to membrane, where cPLA2 cleaves arachidonic acid from natural membrane. Phosphorylation of cPLA2 by MAPK (p42/44 and p38) at serine 505 and serine 727 stimulates its catalytic activity. Applications: Suitable for use in Western Blot and Immunoprecipitation.
