WebJan 4, 2024 · Loss of WRN expression via RNA interference or gene KO, as well as inhibition of WRN’s helicase activity, triggers an increase in DNA damage accompanied by ATM and CHK2 activation. WebChk2 is the mammalian orthologue of the budding yeast Rad53 and fission yeast Cds1 checkpoint kinases (1-3). The amino-terminal domain of Chk2 contains a series of seven serine or threonine residues (Ser19, Thr26, Ser28, Ser33, Ser35, Ser50, and Thr68) each followed by glutamine (SQ or TQ motif).
WebIncreased nuclear p-Chk2-Thr 68 and Ca 2+ /CaM accumulations were found in FIR-irradiated cells, as observed in confocal microscopic analyses and cell fractionation assays. In silico analysis predicted that Chk2 possesses a Ca 2+ /calmodulin (CaM) binding motif ahead of its kinase domain. Chk2 is the mammalian orthologue of the budding yeast Rad53 and fission yeast Cds1 checkpoint kinases (1-3). The amino-terminal domain of Chk2 contains a series of seven serine or threonine residues (Ser19, Thr26, Ser28, Ser33, Ser35, Ser50, and Thr68) each followed by glutamine (SQ or TQ motif).
WebFeb 3, 2014 · Chk2 is phosphorylated at Thr68 by DNA-PKcs during mitosis. Chk2 is the key downstream effector of the ATM signaling pathway for cell cycle checkpoint regulation in the DNA damage response. 26 In ... WebThe amino-terminal domain of Chk2 contains a series of seven serine or threonine residues (Ser19, Thr26, Ser28, Ser33, Ser35, Ser50 and Thr68) followed by glutamine (SQ or TQ motif). These are known to be preferred sites for phosphorylation by ATM/ATR kinases (8).
WebWestern blot was employed to detect the expression of BQ, p-CHK2 (Thr68) and CHK2. GAPDH was used as the loading control. (E) Knockdown of CHK2 could abolish the effect of CCT241533 on reversing TAM resistance. LCC2 and AK-47 were treated with 10 nM of CCT241533 and 4 µM of TAM for 96 h. Cell viability was determined by MTT assay.
