Gene Snapshot
Lipid storage droplet-2 (Lsd-2) encodes a protein associated with lipid droplets. It acts as a barrier for lipases (such as the product of bmm) and thus prevents the mobilization of lipid stores. It is involved in regulation of lipid storage amount and energy homeostasis and acts in concert with the product of Lsd-1. [Date last reviewed: 2019-03-14]

Additional Descriptive Data
Lsd-2 transcript is expressed in the wing pouch of wandering third instar larvae; expression is more pronounced in a strong band with a weaker juxtaposed band along the anterior-posterior compartment boundary, and excluded from the dorsal-ventral compartment boundary. Lsd-2 transcript is also expressed in the presumptive notum.
Maternally contributed Lsd-2 transcript is detected ubiquitously in pre-cellular blastoderm embryos. In cellular blastoderm the transcript is only detected in germ cells. During germ band contraction expression is detected in the amnioserosa and anterior of the midgut as well as the fat body. During third instar Lsd-2 is detected exclusively in the fat body.
Northern analysis demonstrates that Lsd-2 transcript levels are highest in early embryos (0-3 hours AEL), third instar larvae, and adults.

Additional Descriptive Data
Lsd-2 protein is expressed in the wing pouch of wandering third instar larvae; expression is excluded from the dorsal-ventral compartment boundary. Lsd-2 protein is also expressed in the presumptive notum. Lsd-2 protein is restricted to the epithelial cell layer of the wing disc, and does not colocalize with adepithelial-expressed twi protein.
A GFP-Lsd-2 fusion protein was used to determine that Lsd-2 protein was associated with fat droplets and vesicles in the third instar larval fat body.
