ScerGAL4GSG1261 drives mifepristone-inducible expression primarily in neurons and glial cells. Strong expression is observed in cell clusters localized laterally, ventrally, and at the dorsal midline in the ventral nerve cord. Expression is observed in a few cells, possibly glial, in the brain hemispheres. Moderate expression is observed in chordotonal organs, particularly in the sheath cells and insertion sites. Strong expression is observed at neuromuscular junctions of muscles 1, 2, 3, 6, 7, 9, 10, 12, 13, 15 and 16, with some expression in NMJs of most/all muscles. Moderate expression is observed in multidendritic neurons. Expression is observed in oenocytes. There is moderate uninduced expression in the salivary glands, and in chordotonal organ sheath cells.
