Mutation detailsExon 5 encoding the transmembrane domain and 7 of the 9 exons encoding cytoplamic domains were replaced with a neomycin cassette. In addition, the inserted neomycin gene introduced a stop codon. Immunohistochemical staining showed a lack of protein expression in the spleens of homozygous mutant mice. (J:27236, J:100523)
