UAS regulatory sequences drive expression of human androgen receptor (Hsap\AR) in which the polyglutamine repeats are expanded from 20 to 52, tagged at the N-terminal end with a nuclear export sequence (Tag:NES(xMAPKK)).
Animals expressing Hsap\ARQ52.Scer\UAS.T:Xlae\nes under the control of Scer\GAL4GMR.PY, do not show any disruption of adult eye morphology, even in the presence of the androgen receptor ligand, dihydroxytestosterone.
