Modulator of adipocyte lipid metabolism. Coats lipid storage droplets to protect them from breakdown by hormone-sensitive lipase (HSL). Its absence may result in leanness. Plays a role in unilocular lipid droplet formation by activating CIDEC. Their interaction promotes lipid droplet enlargement and directional net neutral lipid transfer. May modulate lipolysis and triglyceride levels (By similarity).
Major cAMP-dependent protein kinase substrate in adipocytes, also dephosphorylated by PP1. When phosphorylated, may be maximally sensitive to HSL. When unphosphorylated, may play a role in the inhibition of lipolysis, by acting as a barrier in lipid droplet.
The N-terminus is blocked.
Belongs to the perilipin family.
Adipocytes.
