| molecularNote | A loxP site was inserted into intron 15. Aspartic acid codon 633 (GAC) in exon 17 was changed to alanine (GCC) (p.D633A). An FRT site flanked neomycin resistance gene cassette and a second a loxP site were inserted into intron 17. Flp-mediated recombination removed the neo cassette. |
