Positive GRASP (GFP reconstitution across synaptic partners) signals between adult Hugin neurons labelled with EcollexAGMR61H10 and neurons labelled with ScerGAL4VT039046 were observed in the adult subesophageal zone, near the esophagus, and along the midline of the brain. GRASP signals were also observed between descending projections of Hugin neurons labelled with EcollexAGMR61H10 and motor neurons labelled with ScerGAL4VGlut-OK371 in the thoracic and abdominal ganglia.
Although alleles from the Janelia Farm lexA driver collection incorporate the same enhancer fragments used to create the Janelia Farm GAL4 driver alleles (GMR_Brain_exp_1), significant differences are frequently observed in the expression pattern of a given enhancer fragment inserted in the P{CaryP}attP40 or other docking site compared to the same fragment inserted in the P{CaryP}attP2 docking site. Generally the Ecol\lexA patterns are subsets of the Scer\GAL4 patterns.
