Summary

Using a nucleus-free DNA replication system, the roles of Xenopus ATR (XATR) and Hus1 (Xhus1) as the DNA replication checkpoint sensors are investigated and it is found that Xhus1 associates with chromatin in unperturbed S phase and dissociates from chromatin following completion of DNA replication.
