cPLA2 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. Expressed in various tissues such as macrophages, platelets, neutrophils, fibroblasts and lung endothelium. Note: This description may include information from UniProtKB.
