WitrynaThese stochastic models of origin firing require dormant origin signaling that inhibits origin firing and suppresses licensed origins for passive replication at a distance of ∼7-120 kbp around replication forks. ATR and CHK1 kinase inhibitors increase origin firing and increase origin density in unperturbed cells. WitrynaA better understanding of DNA replication initiation in human cells and how this process is altered upon DNA replication stress requires the ability to study origin firing genome wide.
