The Role of Single-stranded DNA and Polymerase α in Establishing the ATR, Hus1 DNA Replication Checkpoint*
Explore this paper's citation graph
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.
