Description

UASt regulatory sequences drive expression of Hsap\ATXN3 with the normal polyQ tract of 22 repeats. All Lys residues in the coding sequence have been mutated to Arg. The coding sequence is tagged at the C-terminal with Tag:polyHis.

      Scer\GAL4GMR.PF/Hsap\ATXN3K-null.UAS.Tag:polyHis partially rescues Hsap\ATXN3tr.Q78.UAS.Tag:HA

      (Tsou et al., 2013)
      Comments

      Co-expression of non-ubiquitinatable Hsap\ATXN3K-null.Scer\UAS.T:Zzzz\His6 partially suppresses 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). However, by 2 weeks of age the potency of Hsap\ATXN3K-null.Scer\UAS.T:Zzzz\His6 to suppress degeneration is markedly lower than that of Hsap\ATXN3Scer\UAS.T:Zzzz\His6 or Hsap\ATXN3K117.Scer\UAS.T:Zzzz\His6 transgenes. These flies still display severe eye degeneration and reduced retinal depth.
