UASt regulatory sequences are fused upstream of sequence encoding an AUG start codon, the EGFP coding sequence and 50 GlyAla dipeptide repeats (the codons used avoid generating the pathogenic GGGGCC combination).
Expression of Zzzz\poly-GA50.Scer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4GMR.PU does not lead to any apparent degenerative eye phenotype, as compared to controls.
Expressing Zzzz\poly-GA50.UAS.EGFP under the control of Scer\GAL4GMR.PF does not induce pupal lethality or visible eyes defects in Atx2KI.GFP, Atx2KI.ΔmIDR-GFP or Atx2KI.ΔcIDR-GFP homozygotes at either 18[o]C or 22[o]C.
