Perilipin 2 belongs to the Perilipin family, which consists of proteins that coat intracellular lipid storage droplets. Perilipin 2 in particular is involved in lipid globule surface membrane composition, and has also been implicated in the development and maintenance of adipose tissue. Contrary to previous findings, Perilipin 2 is found in a variety of cells aside from adipocytes, ranging from fibroblasts to skin cells.
