UAS regulatory sequences drive expression of full-length Antp, with the naturally occurring long linker (8 amino acid residues) between the YPWM motif and the homeodomain. The en repressor domain has been fused to the C-terminal end of the protein.
embryonic head, with Scer\GAL4nullo.PG
T1 beard, with Scer\GAL4nullo.PG
Expression of AntpScer\UAS.YPWM.LL.T:en-Rep under the control of Scer\GAL4nullo.PG results in head involution defects and repression of the prothoracic beard.
