Expression of CG5961G4347 driven by Scer\GAL4GMR.PF at 25[o]C leads to a significant decrease in ommatidia and bristle number in the fly eye, compared to lacZ controls; this phenotype is further enhanced at 29[o]C. Expression of CG5961G4347 driven by Scer\GAL4Ddc.PU significantly decreases lifespan in flies, compared to lacZ controls.
