| Enzyme Function | FUNCTION: 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). {ECO:0000250}. |

| Post Translational Modification | PTM: 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. {ECO:0000269|PubMed:9755872}.; PTM: The N-terminus is blocked. |
