Gene Snapshot
Lipid storage droplet-1 (Lsd-1) encodes a protein associated with lipid droplets. It protects lipid droplets from lipase mediated remobilization and facilitates lipolysis by serving as an anchoring point for lipases such as the one encoded by Hsl. It is involved in lipid storage amount regulation and energy homeostasis in concert with the product of Lsd-2. [Date last reviewed: 2019-03-14]

Lsd-1 modulates the access of proteins to the lipid droplet surface, shapes lipid droplet structure and has a role in regulation of lipid storage.

The Hrp59 protein binds preferentially to a subset of mRNAs, including Lsd-1 mRNA.
