UAS regulatory sequences drive expression of a mutant form of abd-A in which amino acids 201-211 (KEINEQARRDR) have been deleted. The construct is tagged with Tag:MYC.
Expressing abd-AURΔ.Scer\UAS.T:Hsap\MYC ubiquitously under the control of Scer\GAL4arm.PS does not result in homeotic transformation of the embryonic thoracic segments.
