Presynaptic expression of ExnScer\UAS.T:Avic\GFP-EYFP driven by the pan-neuronal driver Scer\GAL4elav-C155 in either a GluRIIASP16; ExnEY01953 or a GluRIIASP16; ExnEY-Δ23 double mutant background is sufficient to fully rescue the ExnEY01953 and ExnEY-Δ23 specific components, respectively, in the abnormal neuromuscular junction synaptic homeostasis phenotypes associated with GluRIIASP16; ExnEY01953 and GluRIIASP16; ExnEY-Δ23 double mutants.
