ScerGAL4GSG3630 drives primarily neuronal mifepristone-inducible expression. Weak expression is observed in a subset of cells in the ventral nerve cord: 0-3 cells/hemisegment at dorsal midline, 0-5 lateral cells/hemisegment, 0-5+ ventral cells/hemisegment, frequently including 2 cells/hemisegment at ventral midline in anterior segments. This expression is variable, stronger in anterior segments and is frequently missing from posterior segments. Expression is observed in longitudinal intersegmental processes that project below the Fas2-positive DL fascicle, but above the VL fascicle. Strong expression is observed in the mushroom bodies. Moderate expression is observed in a few other cells in the brain, with weak expression in cells that might be glia. Occasional weak expression is observed in 1-2 chordotonal neurons, and in neuromuscular junctions on muscles 6, 7, 12 and 13.
