Cytosolic phospholipase
WebSep 7, 2010 · Cytosolic phospholipase A2 alpha structure and activation. The binding of calcium (Ca 2+) ions to the CalB motif of the C2 domain promotes the translocation of cPLA 2 α from the cytosol to the perinuclear/membrane region of the cell. Following this change in subcellular localization, cPLA 2 α is phosphorylated on key serine residues of the … WebPhospholipase a2 activity. Specific Function. Selectively hydrolyzes arachidonyl phospholipids in the sn-2 position releasing arachidonic acid. Together with its lysophospholipid activity, it is implicated in the initiation of the inflammatory response. Pfam Domain Function.
