Amino acid 345 was targeted for an arginine to tryptophan mutation (R345W) by changing a CGA codon to a TGG codon within exon 10. An upstream BsmI restriction site 4 bp upstream of the codon was also mutated to aid in genotype screening, and a floxed neomycin resistance cassette was inserted into intron 11 for colony selection. Germline-transmitting chimeras were bred with Cre-transgenic mice to delete the neo cassette. Mutant protein was detected in the retina of homozygote mice by immunohistochemistry. (J:129902)
