UASt regulatory sequences drive expression of Hsap\AR coding sequences carrying a polyglutamine-tract of 65 residues and two phosphomimetic substitutions (S210D and S790D) that prevent dihydrotestosterone binding to Hsap\AR.
Expression of Hsap\ARQ65.S210D.S790D.Scer\UAS in the developing eye under the control of Scer\GAL4GMR.PF has no effect on development, even in the presence of dihydrotestosterone.
