UAS regulatory sequences drive expression of amino acids 1-324 of Scr fused to amino acids 195-270 of Mmus\Hoxa5.
Expression of Scr::Mmus\Hoxa5Scr-Hoxa5.Scer\UAS under the control of Scer\GAL4arm.PU results in ectopic T1 beards. Ectopic tarsi are seen when Scr::Mmus\Hoxa5Scr-Hoxa5.Scer\UAS is expressed under the control of Scer\GAL4dpp.PU.
Scer\GAL4pb.PJ, Scr::Mmus\Hoxa5Scr-Hoxa5.UAS, pbUAS.EGFP has proboscis | ectopic phenotype
Co-expression of Scr::Mmus\Hoxa5Scr-Hoxa5.Scer\UAS and pbScer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4pb.PJ results in a strong transformation of the antenna to proboscis.
