UAS regulatory sequences drive expression of a synthetic version of Antp which lacks the N-terminal domain. The protein consists of the YPWM motif and the homeodomain, followed by a truncated C-terminal domain (lacking the terminal 14 residues). The naturally occurring short linker (4 amino acid residues) is present between the YPWM motif and the homeodomain. A EGFP tag has been fused to the C-terminal end of the protein.
Expression of AntpSynth.Scer\UAS.YPWM.SL.T:Avic\GFP-EGFP under the control of Scer\GAL4nullo.PG results in transformation of head to mesothorax. The mutant embryos show head involution defects and repression of the prothoracic beard.
Expression of AntpSynth.Scer\UAS.YPWM.SL.T:Avic\GFP-EGFP under the control of Scer\GAL4Dll.PU results in transformation of the antenna to tarsal identity.
AntpSynth.UAS.YPWM.SL.EGFP, Scer\GAL4dpp.blk1, toyD2 has visible | homeotic phenotype
AntpSynth.UAS.YPWM.SL.EGFP, Scer\GAL4dpp.blk1, toyD2 has eye phenotype
AntpSynth.UAS.YPWM.SL.EGFP, Scer\GAL4dpp.blk1, toyD2 has wing | ectopic phenotype
Animals expressing AntpSynth.Scer\UAS.YPWM.SL.T:Avic\GFP-EGFP under the control of Scer\GAL4dpp.blk1 in a toyD2 background show eye-to-wing transformations.
