UASt regulatory sequences drive expression of a mutant form of rl in which the glutamic acid at amino acid 335 has been replaced by lysine.
visible | adult stage, with Scer\GAL4GMR.PS
eye, with Scer\GAL4GMR.PS
Expression of rlE335K.Scer\UAS under the control of Scer\GAL4GMR.PS induces weakly abnormal eye development. The phenotype is stronger than is seen when wild type rl (rlScer\UAS.cMa) is expressed.
