GMR regulatory sequences drive expression of the QF2w driver variant of Ncra\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.
NcraQFQF2w.GMR drives expression in the eye disc posterior to the morphogenetic furrow.
Adults carrying Ncra\QFQF2w.GMR have morphologically normal eyes.
