UAS regulatory sequences drive expression of the ds intracellular domain (nucleotides 10153..11464, GenBank:L08811.2). The protein is tagged at the C-terminal end with Tag:V5.
Expressing dsintra.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4hh.PU results in smaller relative posterior wing compartment area and smaller anterior-posterior cross-vein distance, as compared to controls.
Expressing dsintra.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4en.PU
leads to smaller posterior compartment of third instar larval wing discs without affecting apoptosis, as compared to controls.
Expression of dsintra.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4hh.PU in a ds38k/ds36D background leads to high lethality during early pupal stages, with only a few adult survivors that show severe wing defects, as compared to ds38k/ds36D controls.
dsintra.UAS.Tag:V5 fails to rescue ds38k/dsD36
Expression of dsintra.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4hh.PU fails to rescue the wing defects of ds38k/ds36D adults.
