UASt regulatory sequences drive expression of full-length Hsap\ATXN3 with a normal length polyQ repeat of Q27 and with a mutation in each UIM domain (amino acid replacements S236A and S256A). The Hsap\ATXN3 sequence is tagged at the N-terminal end with Tag:MYC.
Co-expression of Hsap\MJDfl.Q27.UIMmut.Scer\UAS.T:Hsap\MYC partially suppresses the eye degeneration phenotype caused by Hsap\MJDtr.Q78.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4GMR.PF.
