RTF2 and CLASPIN localize CHK1 to the replication fork to control S-phase progression

The essential kinase ataxia telangiectasia and Rad3-related (ATR) monitors the replicative (S) phase of the cell cycle to ensure faithful propagation of genetic material. While much is known about the mechanisms governing ATR activity at replication forks, how its effector checkp...
