Expression of DopRScer\UAS.cKa under the control of Scer\GAL4ey-OK107 in a homozygous DopRf02676 background (which will also result in the expression of DopR from the Scer\UAS regulatory sequences present in the insertion in DopRf02676) results in a severe defect in long-term olfactory memory measured 24 hours after spaced repetitive training.
Scer\GAL4Alp4-c232/Dop1R1UAS.cKa fails to rescue Dop1R1f02676
Dop1R1UAS.cKa/Scer\GAL417d fails to rescue Dop1R1f02676
Scer\GAL4Tab2-201Y/Dop1R1UAS.cKa fails to rescue Dop1R1f02676
Flies of the genotype Scer\GAL45.30/+; DopRf02676/DopRf02676 show selectively restored expression of DopR. Those flies that had restored expression in patterns that include the R2/R4 class ellipsoid body neurons exhibit rescue of ethanol-induced hyperactivity. Restoring DopR expression in the R3 neurons of the ellipsoid body neurons (through Scer\GAL4lilli-189Y) results in a modest but statistically significant increase in ethanol-induced hyperactivity. However, expression with Scer\GAL4Aph-4-c232 has no effect on ethanol induced hyperactivity in DopRf02676 homozygous mutants.
