      Expression of Nrg167ΔFIGQY 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 Nrg167ΔFIGQY 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.

      Comments

      Expression of Nrg167ΔFIGQY fully rescues Nrgl4 mutant embryonic lethality. The axonal and NMJ defects seen in Nrgl4 mutant larval motorneuron clones are also fully rescued and similar rates of innervation are seen for all four major classes of motorneurons (SNc/d, SNb, SNa and ISN) as controls.

      Expression of Nrg167ΔFIGQY fully rescues Nrgl7 mutant embryonic lethality.
