anterior fascicle & synapse, with Scer\GAL4elav-C155
Mutant larvae expressing Bj1EP3630 under the control of Scer\GAL4elav-C155 have reduced or abnormal synapses. The ISNb is sometimes absent. Mutant larvae expressing Bj1EP3630 under the control of Scer\GAL4elav-C155 have ISN neuron pathfinding defects. The ISN sometimes innervates the VLMs.
The lethality and CNS phenotype is reverted by excision of the P{EP} element.
