The P{EP} element is inserted within the first intron, downstream of the exon encoding the STG start codon and signal sequence.

Mutant flies fail to habituate in an olfactory startle response assay.
Expression of Nrx-IVEP809 under the control of Scer\GAL4ptc-559.1 (the animals are initially raised at 18oC and then shifted to 29oC after 10 days) results in a reduced number of early germ cells (stem cells, gonialblasts and spermatogonia) in the testis.
Mutant larvae expressing Nrx-IVEP809 under the control of Scer\GAL4elav-C155 have ISN neuron pathfinding defects. Mutant larvae expressing Nrx-IVEP809 under the control of Scer\GAL4elav-C155 have excessive or ectopic synapses.
