| molecularNote | A loxP site was inserted upstream of exon 4. An FRT- and loxP-flanked neo cassette was inserted downstream of exon 4. Cre-mediated recombination removed exon 4 and the neo cassette. Western blot analysis confirmed the absence of protein expression in mouse embryonic fibroblasts. |
