LPCAT2 (Lysophosphatidylcholine Acyltransferase 2): LPCAT2 is an enzyme that plays a crucial role in the biosynthesis and remodeling of phospholipids, key components of cellular membranes. Located mainly in the endoplasmic reticulum, LPCAT2 regulates lipid metabolism and helps maintain membrane integrity. It catalyzes the acylation of lysophosphatidylcholine (LPC) to produce phosphatidylcholine (PC), an essential phospholipid in cell membranes, influencing membrane composition and function.
