UAS regulatory sequences drive expression of most of the region between the ATG codon identified in FBrf0208057 in the tow A1 isoform and that identified in FBrf0202398 in the tow GH12583 cDNA.
Expression of towΔC.Scer\UAS under the control of Scer\GAL4sd.PU does not result in a proximal fusion of wing veins 3 and 4 or a multiple wing hair phenotype.
