UAS regulatory elements drive expression of Hsap\ATXN3 coding sequences in which the arginine/lysine-rich binding site (that binds Hsap\VCP) is mutated.
Expression of Hsap\MJDQ71.HNHH.Scer\UAS, in the eye, under the control of Scer\GAL4elav-C155 results in a reduction of photoreceptor neurons in ommatidia in 14-day old flies (4.5 photoreceptor cells on average per ommatidia, compared to 7 in wild-type).
Co-expression of Hsap\VCPScer\UAS.cBa with Hsap\MJDQ71.HNHH.Scer\UAS, in the eye, under the control of Scer\GAL4elav-C155, partially suppresses the photoreceptor degeneration phenotype of Hsap\MJDQ71.HNHH.Scer\UAS (on average 5.5 photoreceptor cells per ommatidia are present, compared to 4.5 in Hsap\MJDQ71.HNHH.Scer\UAS mutants and 7 in wild-type).
