UAS regulatory sequences drive expression of a mutant form of abd-A in which the KEINEQ amino acid motif starting at position 201 has been replaced with alanines. The construct is tagged with Tag:MYC.
Expressing abd-AUA.Scer\UAS.T:Hsap\MYC ubiquitously under the control of Scer\GAL4arm.PS does not result in homeotic transformation of the embryonic thoracic segments.
