WebDec 30, 2008 · Chk1 is a critical transducer of signals that arise at exogenously induced DNA strand breaks, but is also required for normal cell growth ( 1 ). Chk1 appears to … WebIn the short term, this research uncovers a mechanism by which PRIMPOL can be quickly regulated—by regulating CHK1 activity—which will be important for the field to understand the replication stress repose in greater detail. The work provides a foundation for us and others in the field to investigate strand-specific DNA repair mechanisms.
WebJun 17, 2024 · Chk1 inhibition leads to S-phase apoptosis or death in mitosis. We provide a potential efficacy biomarker and combination therapy to follow-up in clinical setting. Introduction WebMay 1, 2024 · Furthermore, depletion of TRAF4 impaired CHK1 activity and sensitized CRC cells to fluorouracil and other chemotherapeutic agents in vitro and in vivo. These data reveal two novel steps required for CHK1 activation in which TRAF4 serves as a critical intermediary and suggest that inhibition of the ATR–TRAF4–CHK1 signaling may …
WebMay 6, 2024 · CHK1 holds a closed conformation by the interaction between N-terminal kinase domain and C-terminal regulatory domain; while mutations in conserved motifs CM1 or CM2 could destroy this closed conformation, exposing its kinase domain and thus activating CHK1. 8 Indeed, analysis of kinase activity showed that CHK1 mutants …
WebMar 29, 2024 · The anticancer activity and action of olaparib combined with inhibitors of the ATR/CHK1 pathway (ceralasertib as ATRi, MK-8776 as CHK1i) in olaparib-sensitive and -resistant OC cell lines were evaluated. ... Importantly, the addition of ATR/CHK1 pathway inhibitors to olaparib has the potential to overcome acquired resistance to PARPi. … how to take a bias frameCheckpoint 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 … See more Checkpoint kinase 1, commonly referred to as Chk1, is a serine/threonine-specific protein kinase that, in humans, is encoded by the CHEK1 gene. Chk1 coordinates the DNA damage response (DDR) and cell cycle checkpoint … See more In 1993, Beach and associates initially identified Chk1 as a serine/threonine kinase which regulates the G2/M phase transition in fission yeast. Constitutive expression of Chk1 in fission yeast was shown to induce cell cycle arrest. The same gene called … See more DNA damage induces the activation of Chk1 which facilitates the initiation of the DNA damage response (DDR) and cell cycle checkpoints. The DNA damage response is a network of signaling pathways that leads to activation of checkpoints, DNA … See more • CHEK2 • DNA damage checkpoints See more Human Chk1 is located on chromosome 11 on the cytogenic band 11q22-23.
