ScerGAL4GSG4080-1 drives primarily neuronal mifepristone-inducible expression. Strong expression is observed in the ventral nerve cord in ~ 5 cells/hemisegment at dorsal midline, and in lateral, ventral midline and ventral cell clusters. Strong expression is observed in chordotonal organs, and in neuromuscular junctions on most muscle fibers. There is minimal uninduced expression in the salivary glands and in occasional CNS cells.
