Carries an expanded poly-Q tract in the second CAG repeat block with 80 glutamines.
Expression of Hsap\TBP80Q.Scer\UAS in the eye under the control of Scer\GAL4GMR.PU results in the collapse of the eye structure, a loss of pigmentation and severely disorganised photoreceptors. Ommatidial fusion is also observed. The eye defects worsen as flies age.
While flies expressing Hsap\TBP80Q.Scer\UAS under the control of Scer\GAL4elav.PU at young ages perform similarly to aged-matched wild-type flies, they exhibit a late-onset locomotor impairment and exhibit shortened lifespan, as compared to controls.

Expression of Su(H)VDRC.cUa under the control of Scer\GAL4GMR.PU enhances the eye abnormalities caused by the overexpression of Hsap\TBP80Q.Scer\UAS.
Overexpression of Su(H)Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4GMR.PU partially suppresses the eye abnormalities caused by the overexpression of Hsap\TBP80Q.Scer\UAS with an improvement in both the shape and organisation of ommatidia. Ommatidial fusion is no longer observed and pigment loss is less severe.
