      The expression of Rac1DN.UAS.cUa under the control of Scer\GAL4da.G32 leads to severe cuticle defects in the embryo.

      (Silver et al., 2019)

      Flies with expression of Rac1DN.Scer\UAS.cUa driven by Scer\GAL4ics-G4 are more sensitive to ethanol-induced sedation than controls.

      (Ojelade et al., 2015)

      Expression of dominantly negative Rac1DN.Scer\UAS under the control of Scer\GAL4whir3 causes ethanol-sensitivity.

      Reference

      Scer\GAL4ics-G4>Rac1DN.Scer\UAS.cUa;icsG4/icsG4 flies have the same increased sensitivity to ethanol-induced sedation seen in Scer\GAL4ics-G4>Rac1DN.Scer\UAS.cUa flies, unlike ethanol-resistant icsG4/icsG4 flies.

      (Ojelade et al., 2015)

      Overexpression of Rac1DN.Scer\UAS.cUa driven by Scer\GAL4ppk.PU abolishes enhancement of CNS axon regeneration seen in RtcaΔ/RtcaΔ larvae.
