UAS regulatory sequences drive expression of a DsRed(Unk) fluorescent protein. A genomic fragment containing the let-7 pre-miRNA hairpin has been inserted into the DsRed(Unk) 3'UTR.
Expression of let-7Scer\UAS.T:Disc\RFP under the control of Scer\GAL4Bx-MS1096 at 18[o]C results in deformed wings which also show loss of distal wing vein L5.
