Where this comes from

Abstract

The ATR and ATM checkpoint kinases preserve the integrity of replicating chromosomes by preventing the reversal of stalled and terminal replication forks. Hu et al. now show that the ATR pathway targets the Dna2 nuclease to process stalled forks and counteract fork reversal.
