The perilipin family includes lipid droplet-associated protein (perilipin), adipose differentiation-related protein (adipophilin) and TIP47, also known as perilin-3, altogether form the PAT family of proteins. They predominantly localise to the surface of intracellular neutral lipid droplets. Perilipin is a modulator of adipocyte lipid metabolism and adipophilinis and are involved in the development and maintenance of adipose tissue [1,2,3]. This family appears to share some similarity with Pfam:PF08618.
