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 deaminase is thought to arise during RNA polym...

Regulation of RNA transcript elongation in metazoans and its relevance to disease.

The highly orchestrated interactions between elongating Pol II and co-transcriptional RNA-processing factors are discussed, revealing that the splicing factor U1 small nuclear ribonucleoprotein (U1 snRNP) directly stimulates productive elongation.
