The rescue of blocked replication forks is vital to the faithful duplication of a cell's entire genome once per cell cycle. Eukaryotic cells are equipped with the intra-S phase checkpoint that co-ordinates the multitude of cellular responses to replicative stress, and evidence implicate the checkpoint in reflating fork restart by recombination pathways. In this study, I investigate the role of various Schizosaccharomyces pombe checkpoint gene products in the regulation of recombination at forks arrested by a programmed protein barrier, Replication Termination Sequence 1 (RTS1).
