Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: Sequence encompassing a portion of the promoter and exons encoding the initiator methionine, signal peptide, and IgV-like domain were replaced with a neomycin resistance gene inserted by homologous recombination. Neither full length nor truncated transcript was detected by Northern blot or RT-PCR analyses of message isolated from homozygous mutant spleen tissue. (J:84893)
