Expression of Nrg180ΔPDZ in a Nrgl4 mutant background does not result in a significant increase in synaptic retraction in third instar larvae compared to controls. NMJ length is similar to controls, as are bouton number and area.
Flies expressing Nrg180ΔPDZ in a Nrgl4 mutant background establish a normal function of the adult Giant Fibre (GF)-Trochanteral Muscle (TTMn) circuit. There are no significant differences in average response latencies or following frequencies after a train of stimulations at 100 Hz when compared to wild type. No obvious morphological defects are seen at GF terminals.
