Caption B, Targeting strategy for generation of the Rhotm1.1Kpal allele.. Top, mouse opsin consists of five exons (E1-5). The opsin enhancer region 2 kb upstream of the opsin gene is indicated by gray line. 2nd row, the targeting vector contained 6.4 kb of 5' and 1.9 kb of 3' homologous sequence with C to A transversion at codon 23 (A inside arrowhead). Vector backbone sequences are indicated by hatched lines, and Beta-lac stands for the Beta-lactamase gene. 3rd row, as a result of homologous recombination, codon 23 in exon 1 was changed to CAC and the flippase recognition target (FRT)-loxP flanked neomycin resistance gene (Neo) was inserted after exon 1. Bottom row, neomycin was removed from targeted locus by cre-loxP recombination. By this knocking-in method, we generated mice with a point mutation at codon 23, which encode the P23H opsin. This mouse lacks the neomycin cassette but has a 174-bp vector backbone insertion in intron between exon 1 and exon 2.
