UASt regulatory sequences drive expression of an inverted repeat.
Knockdown of Sec23 in the fat body, through expression of Sec23GD7746 under the control of Scer\GAL4Cg.PA causes retention of Avic\GFPvkg-G454 in fat body cells. Avic\GFPvkg-G454 accumulates in growing intracellular aggregates. These eventually coalesce and occupy most of the cytoplasm between the lipid droplets, affecting cell viability. These larvae lack Avic\GFPvkg-G454 in the basement membranes of other organs, such as the wing disc.
Expression under the control of Scer\GAL4Mef2.PR results in late larval lethality.
Expression under the control of Scer\GAL4pnr-MD237 results in lethality before the pupal stage.
