UAS regulatory sequences drive expression of full-length Scr tagged with the triple tag (3xTag:FLAG, Tag:StrepII Tag:CS(TEVp) and Tag:polyHis) after residue 417.
Expression of ScrScer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4arm.PU results in ectopic T1 beards. Ectopic tarsi are seen when ScrScer\UAS.T:Zzzz\FLAG is expressed under the control of Scer\GAL4dpp.PU.
Scer\GAL4pb.PJ/ScrUAS.Tag:FLAG is a non-suppressor of maxillary palp | ectopic phenotype of Scer\GAL4pb.PJ, pbUAS.EGFP
Co-expression of ScrScer\UAS.T:Zzzz\FLAG and pbScer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4pb.PJ does not result in transformation of the antenna to proboscis.
