UAS regulatory sequences drive expression of rpr coding sequences with mutations in the GH3 domain (amino acid replacements F34A and L35A), flanked by rpr 5' and 3' UTRs and tagged at the C-terminus with Tag:HA.
Expression of rprF34A.L35A.Scer\UAS.T:Ivir\HA1 in the developing eye under the control of Scer\GAL4GMR.PF does not affect eye development.
