SWI/SNF complexes as determinants of R-loop metabolism

R-loops—nucleic acid structures composed of an RNA:DNA hybrid and displaced single-stranded DNA—are abundant in the genome and may impair progression of the replication fork, thus leading to accumulation of DNA damage and genome instability. A new study demonstrates that SWI/SNF chromatin-remodeling complexes are instrumental in resolving such R-loop-mediated transcription–replication conflicts, highlighting the importance of these chromatin remodelers in R-loop homeostasis and the maintenance of genome integrity.
