| molecularNote | The L1L2_gt1 cassette was inserted at position 10450152 of Chromosome 3 upstream of the critical exon 2 (Build GRCm39). The cassette is composed of an FRT flanked lacZ/neomycin sequence followed by a loxP site. An additional loxP site is inserted downstream of the targeted exon 2 at position 10451009. Exon 2 is thus flanked by loxP sites. A "conditional ready" (floxed) allele can be created by flp recombinase expression in mice carrying this allele. Subsequent cre expression results in a knockout mouse. If cre expression occurs without flp expression, a reporter knockout mouse will be created. Further information on targeting strategies used for this and other IKMC alleles can be found at http://www.informatics.jax.org/mgihome/nomen/IKMC_schematics.shtml. In J:359000, qPCR analysis demonstrated that mRNA expression is barely detectable in the hippocampus of homozygous mutant mice. |
