WebJul 23, 2009 · PARP1 collaborates with Mre11 to promote replication fork restart after release from replication blocks, most likely by recruiting Mre11 to the replication fork to promote resection of DNA. Both PARP1 and PARP2 are required for hydroxyurea-induced homologous recombination to promote cell survival after replication blocks. WebOct 1, 2024 · Fft3 is needed for efficient DNA resection at blocked replication fork. To assess the mechanistic roles of Fft3 in the process of stressed replication forks, we have used the conditional RTS1-replication fork barrier (RFB) that allows a single replisome to be blocked in a polar manner at a specific locus ().The RTS1-RFB is encoded by the RTS1 …

WebMay 1, 2024 · Resection by MRE11 in wild-type cells contributes to timely fork restart [86], but if forks are unprotected, MRE11, and PARP1 activity, contribute to fork degradation [81].
