Transcription pause and elongation regulators mediate somatic hypermutation

Somatic hypermutation (SHM) creates point mutations in the variable regions of immunoglobulin genes in activated B cells to support antibody affinity maturation1. SHM is initiated by activation-induced deaminase (AID), and the single-stranded DNA substrate of this cytosine deamin...
