| molecularNote | Part of exon 18 and exons 19-20 were replaced with a neomycin resistance gene under the control of a thymidine kinase promoter in reverse orientation. RT-PCR detected a shorter transcript in mutants with exons 16 or 17 spliced to exon 21. Immunohistochemical stainings failed to detect protein in jejunum. |
