nSyb promoter sequences control expression of a QF2w driver (a derivative of QF in which the middle domain is completely deleted and the activation domain is mutated to reduce activity by altering the charge on the C-terminus).
nSyb regulatory sequences control expression of a QF2w driver (this is a weaker transactivator and shows slightly less toxicity compared to the QF2 driver).
Ncra\QFQF2w.nSyb drives pan-neuronal expression; expression is weaker than that of Ncra\QFQF2.nSyb .
lethal | heat sensitive, with shits1.QUAS
viable, with Ncra\QSαTub84B.PP, shits1.QUAS
