G to A nucleotide change at the second or third position of the Trp codon leads to a nonsense mutation (exact site of mutation unspecified). Site of nucleotide substitution in mutant inferred by FlyBase base on reported amino acid change.
Photoreceptor axons do not project correctly in the optic lobe of CkIIαG703 eye-brain complexes in third instar larvae, while the photoreceptor cells themselves are appropriately specified.
Based on heterozygous lethality, these alleles of CkIIα can be placed in the following order, from severe to weak: CkIIαP2 = CkIIαTikR > CkIIαP1 > CkIIαTik > CkIIαH3091 > CkIIαG703.
