No mutation as been detected in the R open reading frame.
R[+]/Rap1E-722 is an enhancer of visible phenotype of cnkCCT.hs.sev
R[+]/Rap1E-722 is an enhancer of eye phenotype of cnkCCT.hs.sev
R[+]/Rap1E-722 is an enhancer of eye photoreceptor cell phenotype of cnkCCT.hs.sev
RE-722 dominantly enhances the rough eye phenotype seen in flies expressing cnkCCT.hs.sev. In addition, the double mutant flies show an increased loss of photoreceptor cells compared to cnkCCT.hs.sev single mutants.
