Amino acid replacement: S210D.
UASt regulatory sequences drive expression of Hsap\AR coding sequences carrying a polyglutamine-tract of 65 residues and two phosphomimetic substitutions that prevent dihydrotestosterone binding to Hsap\AR.
Amino acid replacement: S790D.
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.
