Stated to mediate overexpression of Hr38.
DeltaDN.UAS, Hr38[+]/Hr38d10593, Scer\GAL434B has lethal phenotype
Hr38[+]/Hr38d10593, Scer\GAL4GMR.PF is an enhancer of eye phenotype of DeltaUAS.cJa, Scer\GAL4GMR.PF
Hr38[+]/Hr38d10593, Scer\GAL4GMR.PF is an enhancer of cone cell | pupal stage phenotype of DeltaUAS.cJa, Scer\GAL4GMR.PF
Hr38[+]/Hr38d10593, Scer\GAL4bbg-C96 is an enhancer of wing margin phenotype of DeltaDN.UAS, Scer\GAL4bbg-C96
Scer\GAL4GMR.PF, DlScer\UAS.cJa flies that are also heterozygous for Hr38d10593 have a smaller eye with loss of pigmentation, more disorganized ommatidia, and a further reduction in the number of cone cells per ommatidium compared to Scer\GAL4GMR.PF, DlScer\UAS.cJa flies.
Hr38d10593/+ results in suppression of the Scer\GAL4bbg-C96, DlD.Scer\UAS wing notching phenotype.
