Mutation detailsThe L1L2_Bact_P cassette was inserted at position 3933594 of Chromosome 10 upstream of the critical exon 5 (Build GRCm39). The cassette is composed of an FRT site followed by lacZ sequence and a loxP site. This first loxP site is followed by neomycin resistance gene under the control of the human beta-actin promoter, SV40 polyA, a second FRT site and a second loxP site. A third loxP site is inserted downstream of the targeted exon(s) at position 3934442. The critical exon(s) is/are thus flanked by loxP sites. Cre mediated recombination removed the neo cassette and exon 5 creating a reporter allele. RT-PCR and immunoblot analysis confirmed the absence of transcript and full length protein, respectively, in homozygous embryos. LacZ expression partially recapitulates endogenous gene expression.
