UAS regulatory sequences drive expression of a short inverted repeat.
Early third instar larvae expressing Sec31HMS00666 under the control of Scer\GAL4Cg.PA display larger lipid droplets in the fat body.
The expression of Sec31HMS00666 under the control of Scer\GAL4SPARC-MI00329-GAL4 (and Dicer-2, for a more efficient RNAi) in the larval fat body induces defective secretion, including intracellular matrix material, as shown by the retention of both secr.GFP and Vkg.GFP.
