UAS regulatory sequences drive expression of a short inverted repeat.
The expression of Rab9FbHMS01364 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 extracellular matrix material, as shown by the retention of both secr.GFP and Vkg.GFP. Expression under the control of Scer\GAL4Cg.PA alone leads to enlarged endoplasmic reticulum exit sites (Sec16.GFP) but not of the cis-Golgi (Grasp65.RFP).
