  • 摘要:Protein WIS is a human gamma3 heavy (H) chain disease immunoglobulin variant whose amino acid sequence is most readily interpreted by postulating that three residues of the amino terminus are followed by a deletion of most of the variable (VH) domain, which ends at the variable-constant (VC) joining region. Then there is a stretch of eight residues, three of which are unusual, while the other five have striking homology to the VC junction sequence. This is followed by a second deletion, which ends at the beginning of the quadruplicated hinge region. These findings are consistent with mutations resulting in deletions of most of the gene coding for the V region and CH1 domain followed by splicing at the VC joining region and at the hinge. These structural features fit well the notion of genetic discontinuity between V and C genes and also suggest similar mechanisms of excision and splicing in the interdomain regions of the C gene of the heavy chain.
