Protein attributes

Sequence length	522 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Modulator of adipocyte lipid metabolism, it coats lipid storage droplets to protect them to be broken down by hormone-sensitive lipase (HSL). Its absence may result in leanness.
Subunit structure	Interacts with ABHD5 By similarity.
Subcellular location	Lipid dropletBy similarity. Note= Lipid droplet surface-associated By similarity.
Tissue specificity	Adipocytes.
Post-translational modification	Major cAMP-dependent protein kinase-substrate in adipocytes, also dephosphorylated by PP1. When phosphorylated, may be maximally sensitive to HSL and when unphosphorylated, may play a role in the inhibition of lipolysis, by acting as a barrier in lipid droplet By similarity.
Sequence similarities	Belongs to the perilipin family.
