Background: Perilipin-2

Perilipin-2/Plin-2, also known as adipose differentiation-related protein (ADFP), ADRP, and adipophilin, is a member of the perilipin family of lipid droplet (LD) proteins that functions in lipid accumulation, lipid storage, and LD formation (1,2). Perilipin-2 is ubiquitously expressed and is the major LD protein of the liver (1-3). Human perilipin-2 is 437 amino acids (aa) in length with a theoretical molecular weight of 48 kDa (1,4). Human and mouse perilipin-2 share 81.8% sequence identity. One defining structural feature of perilipin-2 and other LD-related proteins is formation of amphipathic alpha helices (1,3,5). The perilipin-2 protein contains a PAT (perilipin A, ADRP, TIP47) domain, a 11-mer repeat motif, and a 4-helix bundle (1,5). The PAT domain has a role in triglyceride (TG) stabilization, the 11-mer repeat motif functions in cytoplasmic LD binding, and the 4-helix bundle facilitates membrane binding (5). Unlike LDs coated with other perilipin family members (e.g., perilipin-1 and perilipin-5), LDs coated with perilipin-2 are more permissive to lipolysis and protective of lipids and TGs (1-3). Studies have revealed that perilipin-2 knockout (KO) in mice is associated with resistance to fatty liver disease and diet-induced obesity (1). On the other hand, overexpression of perilipin-2 causes increased lipid and TG accumulation, which is a feature of many metabolic, cardiovascular, and age-related diseases (2). Additional research has found higher levels of perilipin-2 is associated with certain cancers such as colorectal cancer and renal carcinomas, and it may be a useful biomarker for detection (2). Though more research is needed, it is possible that inhibition or blocking of perilipin-2 may be a key strategy to combatting several pathologies (2).
