Rad53 arrests leading and lagging strand DNA synthesis via distinct mechanisms in response to DNA replication stress
Sign Up to like & getrecommendations! Published in 2022 at "BioEssays"
DOI: 10.1002/bies.202200061
Abstract: DNA replication stress threatens ordinary DNA synthesis. The evolutionarily conserved DNA replication stress response pathway involves sensor kinase Mec1/ATR, adaptor protein Mrc1/Claspin, and effector kinase Rad53/Chk1, which spurs a host of changes to stabilize replication… read more here.

DOI: 10.1016/j.celrep.2020.02.018
Abstract: Timely completion of DNA replication is central to accurate cell division and to the maintenance of genomic stability. However, certain DNA-protein interactions can physically impede DNA replication fork progression. Cells remove or bypass these physical… read more here.

DOI: 10.1016/j.celrep.2020.108177
Abstract: Summary Cells coordinate interphase-to-mitosis transition, but recurrent cytogenetic lesions appear at common fragile sites (CFSs), termed CFS expression, in a tissue-specific manner after replication stress, marking regions of instability in cancer. Despite such a distinct… read more here.

DOI: 10.1016/j.celrep.2020.108675
Abstract: DNA replication is challenged by numerous exogenous and endogenous factors that can interfere with the progression of replication forks. Substantial accumulation of single-stranded DNA during DNA replication activates the DNA replication stress checkpoint response that… read more here.
