PBac{nub-lacZ.A} insertion 240bp upstream of the crb transcription start site.
Homozygotes show a strong loss of function phenotype.
crbM11.M2 is an enhancer of visible phenotype of Scer\GAL4GMR.APP, grimUAS.cYa
crbM11.M2 is an enhancer of eye phenotype of Scer\GAL4GMR.APP, grimUAS.cYa
The loss of wing margin and wing vein thickening seen in Df(1)N-8/+ animals is suppressed by crbM11.M2/+.
crbM11.M2 enhances the reduced eye phenotype of animals expressing grimScer\UAS.cYa under the control of Scer\GAL4GMR.T:Hsap\APP.
