To ensure the fidelity of DNA replication, cells activate a stress-response pathway when DNA replication is perturbed. This pathway regulates not only progress through the cell cycle but also transcription, apoptosis, DNA repair/recombination and DNA replication itself. Mounting evidence has suggested that this pathway is important for the maintenance of genomic integrity. Here, we discuss recent findings about how this pathway is activated by replication stress and how it regulates the DNA-replication machinery to alleviate the stress.
