The L1L2_gt2 cassette was inserted at position 179250641 of Chromosome 1 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 exon 2 at position 179251462. The critical exon(s) is/are thus flanked by loxP sites. A null/knockout allele was created by cre recombinase expression in mice carrying the tm1a allele to remove the neo selection cassette and loxP-flanked critical exon(s). (J:213209)
