E2A Expression Stimulates Ig Hypermutation
1 Jul 2006
Abstract excerpt
Ig hypermutation is limited to a region of approximately 2 kb downstream of the transcription start sites of the Ig loci. The process requires transcription and the presence of Ig enhancer sequences, and is initiated by the activation-induced cytidine deaminase (AID)-mediated deamination of cytidine bases. It remains unknown why AID causes mutations selectively in the Ig genes and not in most other transcribed...
