| Outline of Final Research Achievements |
A replication fork collapsed by a break in the template DNA can be rescued by a recombination-mediated pathway, allowing the re-establishment of a functional replication fork. However, it is not well understood how the replisome components are regulated during fork collapse and restart. In this study, I found that Psf2, a subunit of GINS (a replisome factor), is phosphorylated by ATR/ATM upon fork arrest, which is involved in the replication restart.
