Detailed Description
Statement
Reference

Flies expressing Nrg+t25 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 Nrg+t25 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 Nrg+t25 fully rescues Nrgl7 mutant embryonic lethality.
