Anti-ADRP/Perilipin-2 Antibody, clone PAD-1

Perilipin-2 (UniProt: Q99541; also known as Adipophilin, Adipose differentiation-related protein (ADRP)) is encoded by the PLIN2 (also known as ADFP) gene (Gene ID: 123) in human. ADRP/Perilipin-2 is an intracellular neutral lipid droplet (LD) surface protein that belongs to the PAT family of proteins. The N-terminal region contains a highly conserved hydrophobic PAT domain (aa 1-115) that is involved in lipid droplet stabilization, lipid accumulation, and proteasomal degradation, while the conserved C-terminal domain facilitates its binding to lipid droplets. LDs play an active role in lipid homeostasis, lipid synthesis, metabolism, and transportation. ADRP/Perilipin-2 is a gatekeeper protein that is involved in regulating triacylglycerol storage in adipocyte through the suppression of basal lipolysis apparently through protecting triacylglycerol against hydrolysis and it regulates the recruitment of various proteins involved in lipid synthesis and degradation. Its expression profile is notably high in adipose tissue and liver, with varying levels observed in other tissues. ADRP/Perilipin-2 interacts with other lipid metabolism-related proteins, such as hormone-sensitive lipase. Dysregulation of ADRP/Perilipin-2 expression has been implicated in several metabolic disorders, including obesity, insulin resistance, and non-alcoholic fatty liver disease. Moreover, ADRP/Perilipin-2 have been associated with certain cancers, suggesting its involvement in tumorigenesis by modulating lipid metabolism within the tumor microenvironment.
