Additional Information
Statement
Reference

ScerGAL4GSG1694 drives primarily neuronal mifepristone-inducible expression. Strong expression is observed in the ventral nerve cord in a segmentally repeated pattern: ~3-5 cells at the dorsal midline, a laterally localized small cluster of cells, ~2 cells at the ventral midline, and scattered ventral cells in each hemisegment. Moderate expression is observed in scattered cells, possibily glial, in the brain. Strong expression is observed in sensory axons, possibly antennal lobe axons. Moderate expression is observed in a variable number of multidendritic neurons, and weak expression is observed in a subset of lcs5 chordotonal organs. Weak expression is observed at neuromuscular junctions of muscles 1, 2, 3, 4, 6, 7, 15 and 16.
