UAS regulatory sequences drive expression of amino acids 1-194 of Mmus\Hoxa5 fused to amino acids 325-417 of Scr.
Expression of Scr::Mmus\Hoxa5Hoxa5-Scr.Scer\UAS under the control of Scer\GAL4pb.PJ does not result in transformation of the antenna to proboscis.
Expression of Scr::Mmus\Hoxa5Hoxa5-Scr.Scer\UAS under the control of Scer\GAL4rn.PU results in mild induction of ectopic sex combs on the second leg.
Expression of Scr::Mmus\Hoxa5Hoxa5-Scr.Scer\UAS under the control of Scer\GAL4arm.PU results in ectopic T1 beards. Ectopic tarsi are seen when Scr::Mmus\Hoxa5Hoxa5-Scr.Scer\UAS is expressed under the control of Scer\GAL4dpp.PU.
