WebJul 31, 2024 · The CHK1 protein kinase is essential to deal with replication stress (RS) and ensure genome integrity and cell survival, yet how basal levels and activity of CHK1 are maintained under physiological, unstressed conditions is not well understood. WebOct 10, 2005 · Even loss of one copy of Chk1 has severe consequences for cells . Given this fact, we propose that all three of these microcephaly disorders arise through defective regulation of Chk1. This defect in Chk1 function leads to increased cellular lethality in neural lineages and severely decreased brain and head size.
