Mutation detailsTwo point mutations were introduced into exon 4 at codon 91 (CGA to TGG) to cause an arginine to tryptophan missense mutation (R91W). A floxed neomycin resistance cassette was also introduced into intron 6 for targeting purposes. Founder mice were mated with deleter mice to remove the neomycin cassette, leaving behind a single loxP site. Levels of the mutant protein are reduced by 95% compared to wild-type controls as determined by western blots of retinal extracts. (J:130076)
