UASt sequences drive expression of Hsap\ATXN1 without any glutamine-repeat tract, tagged with Tag:FLAG.
Expression of Hsap\ATX10Q.Scer\UAS.T:Zzzz\FLAG, under the control of Scer\GAL4GMR.PF, results in an eye phenotype. The defects include loss of bristles and pigmentation, dented ommatidium, and degeneration of photoreceptors. However, the eye's overall structure and the organization of ommatidia are still maintained. Coexpression of Hsap\BoatScer\UAS.T:Zzzz\FLAG and Hsap\ATX10Q.Scer\UAS.T:Zzzz\FLAG, under the control of Scer\GAL4GMR.PF, causes a more severe eye phenotype, in which eye structure is collapsed and photoreceptors are severely degenerated.
