ScerGAL4GSG3315-1 drives mifepristone-inducible expression primarily in neurons. In the ventral nerve cord, strong expression is observed in lateral clusters of 10-15 interneurons/hemisegment; in intersegmental processes at the Fas2-positive DL fascicle, and lateral to the CI fascicle, and along the VM fascicle. Strong expression is observed in a small cluster of neurons in the central region of the brain with processes that project to the contralateral hemisphere. Expression is observed in chordotonal organ attachment and sheath cells.
Inhibition (using Ctet\tetXTNT-LC.UAS) of Scer\GAL4GSG3315-1 cells significantly reduces larval escape behavior in response to HCl application, compared to controls.
