UASt regulatory sequences drive expression of an inverted repeat.
Flies expressing rkKK108009 under the control of Scer\GAL4GMR.PU have a normal eye phenotype.
The midguts of 10-14 day old flies expressing rkKK108009 under the control of Scer\GAL4how-24B (in combination with a Dicer-2 transgene to enhance RNAi efficiency) display intestinal stem cell hyperproliferation and epithelial multilayering, but these flies do not display developmental defects, as compared with controls.
rkKK108009 is rescued by rkUAS.cSa/Scer\GAL4how-24B
Expression of rkScer\UAS.cSa restores intestinal stem cell quiescence in flies expressing rkKK108009 under the control of Scer\GAL4how-24B.
