Abstract
In the genome, repetitive guanine-rich sequences have the potential to spontaneously fold into non-canonical DNA secondary structures known as G-quadruplex (G4). Using novel single-molecule imaging approaches, the authors reveal that G4 formation within active replication forks locally perturb replisome dynamics and damage response signaling, which require RPA and FANCJ for regulation.
