Although IWS1 has been implicated in transcription-coupled processes, its direct role in RNA polymerase II function remained undefined. Here, the authors demonstrate that IWS1 enhances Pol II elongation velocity by acting as a structural scaffold and promoting co-transcriptional H3K36me3 deposition.
