背景信息

PLIN2 (Perilipin 2), also known as Adipose Differentiation-Related Protein (ADRP), is a lipid droplet-associated protein that plays a critical role in lipid storage and metabolism. As a member of the perilipin family, it is primarily expressed in tissues with active lipid metabolism, including adipose tissue, liver, and macrophages. PLIN2 coats the surface of lipid droplets, stabilizing their structure and regulating lipolysis by interacting with lipases such as adipose triglyceride lipase (ATGL) and hormone-sensitive lipase (HSL). Its expression is upregulated during adipocyte differentiation and in response to lipid overload, making it a key marker for cellular lipid accumulation.

Recombinant PLIN2 protein is engineered in vitro using expression systems like *E. coli* or mammalian cells to produce purified, biologically active forms of the protein for research. This allows scientists to study its structural properties, lipid-binding domains (e.g., the PAT domain), and interactions with other proteins or signaling molecules. Recombinant PLIN2 is widely used to investigate metabolic disorders, including obesity, non-alcoholic fatty liver disease (NAFLD), and atherosclerosis, where dysregulated lipid storage contributes to pathogenesis. It also serves as a tool for developing therapeutic strategies targeting lipid metabolism, such as small-molecule inhibitors or gene-editing approaches. Additionally, recombinant PLIN2 is utilized in diagnostic assays, antibody validation, and cell-based studies to model lipid droplet dynamics under various metabolic conditions. Its study provides insights into cellular energy homeostasis and the molecular mechanisms linking lipid dysregulation to chronic diseases.
