Phospholipase A2 Group III (PLA2G3) is an enzyme that plays a crucial role in the metabolism of phospholipids, which are essential components of cell membranes. It catalyzes the hydrolysis of phospholipids, releasing fatty acids and lysophospholipids. This process is important for various physiological functions, including inflammation and cell signaling. PLA2G3 is found in various tissues and is associated with several biological processes, such as immune responses and lipid metabolism. Its activity can influence the production of bioactive lipids, which are involved in regulating cellular functions and responses to stress. Understanding PLA2G3 can provide insights into its potential roles in health and disease.
