A loxP site was inserted just upstream of exon 2 (containing the ATG start codon). A floxed neomycin resistance cassette was also inserted in intron 3. The resistance cassette was removed prior to blastocyst injection, presumably by transient cre excision. This left exons 2 and 3 flanked by loxP sites. (J:167430)
