WebCytosolic phospholipase A2 is an enzyme that in humans is encoded by the PLA2G4A gene. [5] [6] Function [ edit] This gene encodes 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. WebCytosolic phospholipase A 2 (cPLA2) is a calcium-dependent enzyme that cleaves fatty acids, such as arachidonic acid, from phospholipids by hydrolyzing the SN-2 acyl bond …
