UASt regulatory sequences drive expression of a poly-glutamine-repeat encode by 20 CAA codons fused with C-terminal Tag:MYC and Tag:FLAG tags.
Expression of Zzzz\CAGCAA.20.Scer\UAS.T:Hsap\MYC,T:Zzzz\FLAG in the developing eye under the control of Scer\GAL4GMR.PF has no apparent effect on the external morphology of the eye when compared with controls.
