Amino acid replacement: K117?.
UASt regulatory sequences drive expression of Hsap\ATXN3 coding sequences where the lysine at position 117 (which is ubiquitinated in cells) is mutated. Tagged at the C-terminal with Tag:polyHis.
Expression of Hsap\ATXN3K117.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\ATXN3K117.Scer\UAS.T:Zzzz\His6 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).
