UAS regulatory sequences drive expression of exd which is tagged at the N-terminal end with C155-Venus. A linker of 5 amino acid residues separates the exd and C155-Venus sequences. The fusion protein is also tagged with a Tag:HA epitope.
exdUAS.VCE.C155-Venus,Tag:HA/Scer\GAL4Ubx-M1 rescues exd1
Expression of exdScer\UAS.VCE.T:Avic\GFP-VC,T:Ivir\HA1 under the control of Scer\GAL4Ubx-M1 rescues the abdominal segment phenotypes of exd1 embryos.
