Sequences encoding a GAL4::VP16 driver are separated from an arm promoter by an FRT cassette containing a y marker.
Designed for use in mosaic analyses; transcription blocked by FRT-flanked fragment carrying y+M. See expression pattern for ScerGAL4arm.T:HsimVP16RA, carried in descendant transposon P{GAL4-arm(-FRT).VP16}.
