UASt regulatory sequences drive expression of Hsap\ATXN3 with the normal polyQ tract of 22 repeats. The protein carries a mutation in the catalytic cysteine (amino acid replacement C14A) and is tagged at the C-terminal end with Tag:polyHis.
Expression of Hsap\ATXN3C14A.Scer\UAS.T:Zzzz\His6 in the developing eye, under the control of Scer\GAL4GMR.PF does not affect eye development.
Co-expression of Hsap\ATXN3C14A.Scer\UAS.T:Zzzz\His6 does not suppress the protective role of expression of DnaJ-1Scer\UAS.cKa in suppressing eye degeneration in flies with Hsap\ATXN3tr.Q78.Scer\UAS.T:Ivir\HA1 driven by Scer\GAL4GMR.long.
Co-expression of Hsap\ATXN3C14A.Scer\UAS.T:Zzzz\His6 does not significantly suppress eye degeneration seen in flies with expression of Hsap\ATXN3tr.Q78.Scer\UAS.T:Ivir\HA1 driven by Scer\GAL4GMR.long.
Co-expression of Hsap\ATXN3C14A.Scer\UAS.T:Zzzz\His6 does not suppress the eye degeneration seen upon expression of Hsap\ATXN3tr.Q78.Scer\UAS.T:Ivir\HA1 (with both transgenes under the control of Scer\GAL4GMR.PF).
