UASt regulatory sequences drive expression of an inverted repeat.
partially lethal, with Dcr-2UAS.cDa, Scer\GAL4elav.PLu
viable, with Scer\GAL4pnr-MD237
viable, with Scer\GAL4tin.CΔ4
Depending on the insertion line used, expression under the control of Scer\GAL4Mef2.PR can result in viable flies or late pupal lethality.
