Checkpoint kinases (Chks) are protein kinases that are involved in cell cycle control. Two checkpoint kinase subtypes have been identified, Chk1 and Chk2. Chk1 is a central component of genome surveillance pathways and is a key regulator of the cell cycle and cell survival. Chk1 is required for the initiation of DNA damage checkpoints and has recently been shown to play a role in the normal (unperturbed) cell cycle. Chk1 impacts various stages of the cell cycle including th… WebApr 6, 2024 · We checked phosphorylation levels of Chk1 and Chk2 in response to HU exposure (Fig. 5b), which could trigger replication fork stalling and induce DNA damage …
WebFeb 1, 2011 · In human cells, Chk2 appears to be involved in DNA repair by phosphorylating and regulating the tumor suppressor breast cancer 1 (Brca1). When DNA damage occurs, Chk2 phosphorylates Brca1 on serine-988, causing its dissociation from nuclear foci.
WebJan 28, 2024 · The DDR is coordinated by the checkpoint kinases 1 and 2 (CHK1 and CHK2) which act independently to delay cell cycle progression and allow time for DNA repair.
