UAS regulatory sequences drive expression of the stac A isoform which has been mutated to carry the lesion present in the stac3B20 allele. The protein is tagged at the N-terminal end with EGFP.
Scer\GAL4dysf.C1.7/stac3B20.UAS.A.EGFP fails to rescue stac3B20
Expression of stac3B20.Scer\UAS.A.T:Avic\GFP-EGFP under the control of Scer\GAL4dysf.C1.7 fails to rescue the tracheal defects of stac3B20/stac3B20 embryos.
