A neo/ura3 fragment flanked by LoxP sites was used to replace the first three Myo1a exons via yeast-mediated homologous recombination. Absence of protein in mutants was confirmed by immunoblot of small intestines. Immunostaining of mutant duodenal sections with an antibody directed against the TH1 domain showed the expected lack of signal in mutants.
