Genomic fragment (fosmid P52GD2) containing the complete crb transcription unit plus approximately 7kb upstream and 5kb downstream sequence. The coding sequence has been mutated to carry a Y10F amino acid replacement.
Expression of flwScer\UAS.T:Ivir\HA1 under the control of Scer\GAL4332.3 does not lead to any obvious phenotype in embryos expressing crbY10F in a crbGX24w-/crb11A22 background.
