UAS regulatory sequences drive expression of a short inverted repeat.
The expression of Hexo2HMC04581 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.
