Mutant third instar larvae are capable of synaptic homeostasis at the neuromuscular junction, as indicated by an increase in quantal content in the presence of the glutamate receptor antagonist philanthotoxin-433 (10μM).
Arf51FKG02753/Arf51FEP2612 flies are sensitive to ethanol-induced sedation compared to wild-type controls.
Arf51F[+]/Arf6KG02753 is an enhancer of ommatidium phenotype of Scer\GAL4GMR.PF, cindrRNAi.PC.PD.UAS
The sensitivity to ethanol-induced sedation seen in Arf51FKG02753/Arf51FEP2612 flies is not altered if they also carry RhoGAP18B1.
The sensitivity to ethanol-induced sedation seen in Arf51FKG02753/Arf51FEP2612 flies is not altered if they express Rac1CA.Scer\UAS under the control of Scer\GAL4RhoGAP18B-NP1514 specifically in the adult (using the heat sensitive Scer\GAL80ts.αTub84B allele to limit expression).
The ommatidial patterning errors resulting from the expression of cindrdsRNA.PC.PD.Scer\UAS via Scer\GAL4GMR.PF are strongly enhanced in Arf51FKG02753 heterozygotes.
Expression of Arf51FScer\UAS.cCa under the control of Scer\GAL4elav.PLu rescues the sensitivity of Arf51FKG02753/Arf51FEP2612 flies to ethanol-induced sedation.
Expression of Arf51FScer\UAS.cCa under the control of Scer\GAL4RhoGAP18B-NP1514 throughout development but not in the adult (using the heat sensitive Scer\GAL80ts.αTub84B allele to limit expression) does not rescue the sensitivity of Arf51FKG02753/Arf51FEP2612 flies to ethanol-induced sedation.
Expression of Arf51FScer\UAS.cCa under the control of Scer\GAL4RhoGAP18B-NP1514 specifically in the adult (using the heat sensitive Scer\GAL80ts.αTub84B allele to limit expression) does rescue the sensitivity of Arf51FKG02753/Arf51FEP2612 flies to ethanol-induced sedation.
