ScerGAL4GSGB80-3 drives primarily mifepristone-inducible neuronal expression. Moderate expression is observed in the ventral nerve cord in 3-5 cells bodies at the dorsal midline, and in lateral clusters of cells. Weak expression is observed in scattered cells, possibly glial cells, in the brain. Strong expression is observed in chordotonal organs. Weak expression is observed at neuromuscular junctions on muscles 1, 2, 3, 4, 5, 6, 7, 8, 12, 13, 14, 15, 16, 17 and 30.
