LPCAT2 (Lysophosphatidylcholine Acyltransferase 2): LPCAT2 is an enzyme that plays a key role in the biosynthesis and remodeling of phospholipids, which are essential components of cellular membranes. Primarily found in the endoplasmic reticulum, LPCAT2 regulates lipid metabolism and helps preserve membrane integrity. It catalyzes the acylation of lysophosphatidylcholine (LPC) to form phosphatidylcholine (PC), a vital phospholipid in cell membranes, affecting membrane composition and functionality.
