UAS regulatory sequences drive expression of a short inverted repeat.
The expression of VhaPPA1-1HMC04918 under the control of Scer\GAL4SPARC-MI00329-GAL4 (and Dicer-2, for a more efficient RNAi) in the larval fat body leads to defects in general secretion, as shown by the aberrant intracellular accumulation of Vkg.GFP (collagen IV), Trol.GFP, secr.GFP and Vkg.GFP.
