ScerGAL4GSG3601-1 drives mifepristone-inducible expression primarily in neurons and muscles. Strong expression is observed in the dorsal midline, lateral and ventral cell clusters in the ventral nerve cord. Expression is obseved in a few cells in the brain. Weak expression is observed in all muscles. Strong expression is observed at most neuromuscular junctions, localized to type Is and Ib boutons. There is weak uninduced expression.
