背景信息

LPCAT2 (lysophosphatidylcholine acyltransferase 2) is a key enzyme in phospholipid remodeling, a process critical for maintaining membrane structure, signaling, and lipid homeostasis. Belonging to the acyltransferase family, LPCAT2 catalyzes the conversion of lysophosphatidylcholine (LPC) to phosphatidylcholine (PC) by transferring an acyl group from acyl-CoA to the sn-2 position of LPC. This reaction contributes to the Lands’ cycle, a pathway that dynamically adjusts the composition of phospholipids in cellular membranes. Unlike its isoform LPCAT1. which is broadly expressed, LPCAT2 shows restricted expression in immune cells (e.g., macrophages, neutrophils) and is highly responsive to inflammatory stimuli, linking it to immune regulation and pathological conditions.

The enzyme is localized to cellular membranes, including the endoplasmic reticulum and Golgi apparatus, and plays a role in synthesizing pro-inflammatory lipid mediators such as platelet-activating factor (PAF) and arachidonate-containing phospholipids. Studies implicate LPCAT2 in diseases characterized by lipid dysregulation and inflammation, including atherosclerosis, non-alcoholic fatty liver disease (NAFLD), and sepsis. Its upregulation in activated macrophages and involvement in lipid droplet formation highlight its dual role in metabolic and inflammatory pathways.

Recombinant LPCAT2 protein is produced using expression systems like mammalian cells (e.g., HEK293) or E. coli, often fused with tags (e.g., His-tag) for purification. This engineered protein enables in vitro studies of enzymatic activity, substrate specificity, and inhibitor screening. Researchers utilize it to explore mechanisms of lipid metabolism, evaluate therapeutic targets for inflammatory diseases, and develop assays for drug discovery. Its role in generating bioactive lipids makes LPCAT2 a promising focus for modulating inflammation and metabolic disorders, though challenges remain in understanding tissue-specific regulation and isoform redundancy.
