The P{EP} element is inserted within the first intron, upstream of the entire coding region.
anterior fascicle & synapse, with Scer\GAL4elav-C155
Mutant larvae expressing CG10426EP3636 under the control of Scer\GAL4elav-C155 have ISN neuron pathfinding defects.
In the dorsal muscle region of mutant larvae expressing CG10426EP3636 under the control of Scer\GAL4elav-C155 leads to long abnormal branch with bouton -like structures emanating from the ISN and crossing the segmental border.
