Abstract
Chk1 is an evolutionarily conserved protein kinase that functions to ensure genomic integrity upon genotoxic stress. Studies to date have revealed striking similarities among Chk1 pathways of different organisms. In this review we discuss what is known about Chk1 activation and what downstream factors are regulated by Chk1 to counter replication blocks and DNA damage induced by UV, IR, and other genotoxic agents. Where applicable, we also compare the role of Chk1 with that of the Chk2 protein kinase in the checkpoint responses.Entities:
