The 5'UTR and start codon of the rdxA isoform are replaced with a Kozack sequence, a start codon and a Tag:MYC epitope and then cloned downstream of UASt regulatory sequences.
Expression of rdxA.Scer\UAS:T:Myc in the wing pouch, under the regulation of Scer\GAL4Bx-MS1096 generates signalling changes that result in smaller than normal adult wings, with ectopic veins anterior to vein 3.
