ScerGAL4GSG3147-1 drives primarily neuronal mifepristone-inducible expression. Weak expression is observed in the ventral nerve cord in one ventral midline and five ventro-lateral cells/hemisegment. Strong expression is observed in abdominal ventral bipolar neuron vbp (vbd) and class III and IV dendritic arborizing neurons (md-da). Expression is also observed in imaginal discs.
