In Xenopus, Claspin interacts with Chk1 after DNA damage through a region containing two highly conserved repeats, which becomes phosphorylated during the checkpoint response. Because this region is also conserved in human Claspin, we investigated the regulation and function of these potential phosphorylation sites in human Claspin. We found that Claspin is phosphorylated in vivo at Thr-916 in response to replication stress and UV damage. Mutation of these phosphorylation sites on Claspin inhibited Claspin-Chk1 interaction in vivo, impaired Chk1 activation, and induced premature chromatin condensation in cells, indicating a defect in replication checkpoint. In addition, we found that Thr-916 on Claspin is phosphorylated by Chk1, suggesting that Chk1 regulates Claspin during checkpoint response. These results together indicate that phosphorylation of Claspin repeats in human Claspin is important for Claspin function and the regulation of Claspin-Chk1 interaction in human cells."xsd:string |
