UASt regulatory sequences drive expression of an N-terminally deleted form of Hsap\ATXN3(79Q) (Hsap\ATXN3 with a polyglutamine tract of 79 residues) which lacks Hsap\ATXN3 residues 1-128 and is tagged with Tag:MYC.
Adults expressing Hsap\MJDΔN'79QC.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4hs.2sev have a disorganised external morphology of the eye. The arrangement of the photoreceptor cells is disrupted (the trapezoidal organisation of photoreceptors is almost completely absent).
Hsap\ATXN3ΔN'79QC.UAS.Tag:MYC, Scer\GAL4hs.2sev has visible phenotype, suppressible by Mmus\Ube4bUAS.Tag:FLAG, Scer\GAL4hs.2sev
Hsap\ATXN3ΔN'79QC.UAS.Tag:MYC, Scer\GAL4GMR.PF has lethal | pupal stage phenotype, suppressible by Mmus\Ube4bUAS.Tag:FLAG, Scer\GAL4GMR.PF
Hsap\ATXN3ΔN'79QC.UAS.Tag:MYC, Scer\GAL4hs.2sev has eye phenotype, suppressible by Mmus\Ube4bUAS.Tag:FLAG, Scer\GAL4hs.2sev
Co-expression of Mmus\Ube4bScer\UAS.T:Zzzz\FLAG suppresses the pupal lethality caused by expression of Hsap\MJDΔN'79QC.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4GMR.PF. Co-expression of Mmus\Ube4bScer\UAS.T:Zzzz\FLAG suppresses the eye phenotype caused by expression of Hsap\MJDΔN'79QC.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4hs.2sev.
