Scer\GAL4G14/Impβ11UAS.EGFP fails to rescue Impβ1170
Expression of Ranbp11Scer\UAS.T:Avic\GFP-EGFP in photoreceptors under the control of Scer\GAL4ey.PH fully restores the on and off transients in Ranbp1170 mutant eye clones.
Expression of Ranbp11Scer\UAS.T:Avic\GFP-EGFP in photoreceptors under the control of Scer\GAL4ey.PH fully restores the on and off transients in Ranbp119 mutant eye clones.
Expression of Ranbp11Scer\UAS.T:Avic\GFP-EGFP in photoreceptors under the control of Scer\GAL4ey.PH fully restores the on and off transients in Ranbp1124 mutant eye clones.
Expression of Ranbp11Scer\UAS.T:Avic\GFP-EGFP in photoreceptors under the control of Scer\GAL4ey.PH fully restores the on and off transients in Ranbp1120 mutant eye clones.
Expression of Ranbp11Scer\UAS.T:Avic\GFP-EGFP in photoreceptors under the control of Scer\GAL4ey.PH fully restores the on and off transients in Ranbp11202 mutant eye clones.
Expression of Ranbp11Scer\UAS.T:Avic\GFP-EGFP in all tissues (with a Scer\GAL4da.G32 driver) or in neurons (with a Scer\GAL4elav.PLu driver) rescues the reduction in bouton number/muscle surface area in Ranbp1170 mutants. Expression of Ranbp11Scer\UAS.T:Avic\GFP-EGFP in muscle (with a Scer\GAL4G14 driver) does not rescue this phenotype in Ranbp1170 mutants.
The observed defects in quantal content and EJP amplitude in Ranbp1170 are fully rescued upon expression of Ranbp11Scer\UAS.T:Avic\GFP-EGFP in the nervous system under the control of Scer\GAL4elav.PLu. Although quantal content is somewhat increased by transgene expression in muscle (under the control of Scer\GAL4G14), it does not correspond to a statistically significant restoration of EJP amplitude. Separately, neither neuronal nor muscle expression of Ranbp11Scer\UAS.T:Avic\GFP-EGFP is adequate to restore mEJP frequency or amplitude to control levels; however, concurrent expression in both neurons and muscle significantly increases mini frequency. mEJP amplitude is not rescued.
