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 …

Originally identified as a mediator of DNA damage response (DDR), checkpoint kinase 1 (Chk1) has a broader role in checkpoint activation in DDR and normal cell cycle regulation. Chk1 …

DNA damage induces activation of Chk1, which then transduces the checkpoint signal and facilitates cell cycle arrest and DNA damage repair. Significant progress has been made …

Jun 1, 2024 · CHK1 plays a crucial role in cancer biology as it modulates cell cycle checkpoint activation and DNA repair. Furthermore, a number of other cellular functions of CHK1 are also …

Mar 30, 2025 · CHEK1 (Checkpoint Kinase 1) is a Protein Coding gene. Diseases associated with CHEK1 include Oocyte/Zygote/Embryo Maturation Arrest 21 and Lynch Syndrome 2. Among …

Chk1 activation via ATR plays a dominant role in response to replication stresses (the replication checkpoint). Chk1 is also required for amplification of DSB-initiated Cdc25A signaling …

Jan 28, 2021 · Originally identified as a regulator of the G2/M checkpoint, CHK1 has since been shown to play important roles in DNA replication, mitotic progression, DNA repair, and overall …

Mar 1, 2014 · DNA damage induces activation of Chk1, which then transduces the checkpoint signal and facilitates cell cycle arrest and DNA damage repair. Significant progress has been …

Nov 22, 2017 · Despite its essential function, CHK1 has been identified as a target to kill cancer cells and studies using Chk1 haploinsufficient mice initially suggested a role as tumor …

Feb 8, 2025 · Title: Combined Aurora Kinase A and CHK1 Inhibition Enhances Radiosensitivity of Triple-Negative Breast Cancer Through Induction of Apoptosis and Mitotic Catastrophe …
