Abstract excerpt
Immunoglobulin genes undergo somatic hypermutation in activated B lymphocytes. The mutations are targeted to the variable region of the gene, apparently by co-transcriptional deposition of a mutation complex. The novel activation induced deaminase (AID) gene is required for this process and recent work indicates that it is the cytidine deaminase activity of the AID protein rather than an associated RNA editing...
