ScerGAL4GSG3147-2 drives mifepristone-inducible expression primarily neuronally. Moderate expression is observed in anterior segments of the ventral nerve cord, including 5-6 cells per hemisegment at dorsal midline, some of which are A1-7 dorsal motor neurons; lateral clusters of 15+ cells per hemisegment, and 25+ ventral cells per hemisegment. Fewer cells and weaker expression are observed in the posterior VNC. Expression is observed in longitudinal intersegmental processes along DL, VL and CL FasII axon tracts,and along medial processes between DM and VM axon tracts. Moderate expression is observed in 1-2 cells per brain hemisphere; weak expression is observed in cells that may be cortex glia. Weak expression is observed in chordotonal organs. Weak variable expression is observed at neuromuscular junctions.
