UAS regulatory sequences drive expression of a mutant form of abd-A in which the RRDR amino acid motif starting at position 208 has been replaced with alanines. The construct is tagged with Tag:MYC.
Expressing abd-ARA.Scer\UAS.T:Hsap\MYC ubiquitously under the control of Scer\GAL4arm.PS causes homeotic transformations to A2 in segments anterior to the wild type A2 segment, as assessed by denticle pattern.
