UAS regulatory sequences drive expression of an inverted repeat.
Expressing Syx18JF02263 under the control of Scer\GAL4pros-V1 results in larger late endosomes in larval garland cells (Rab7-positive puncta in fluorescence microscopy).
Clonal expression of Syx18JF02263 under the control of Scer\GAL4Act5C.PP (in combination with Dicer-2, for a more efficient RNAi) affects the distribution of autophagic vesicles in the larval fat body (Atg8-positive puncta in fluorescence microscopy).
Expressing Syx18JF02263 under the combined control of Scer\GAL4fkh.PH abolishes glue granules in the larval salivary glands; in agreement, all of the (pre)pupae fell down from the wall of the culture vials.
The expression of Syx18JF02263 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.
