Abstract:DNA replication often encounters obstacles like the stalled transcription machinery and R-loops. While ribonucleases and DNA-RNA helicases can resolve these structures, the role of chromatin remodelers remains understudied. Through a series ofin vitroandin vivoexperiments, we show that the chromatin remodeler SMARCAD1, which associates with active replication forks, is crucial for resolving nearby R-loops to maintain fork stability. SMARCAD1 directly binds R-loops via its ATPase domain and associates with the … Show more
