WebApr 6, 2024 · In contrast, the phosphorylation level of Chk2 at Thr68 (p-Chk2) was comparable in nbn mutant and wild-type under HU treatment (Fig. 5d and Supplementary Fig. 9b), indicating that Chk2 signaling ... The CHEK2 gene encodes for checkpoint kinase 2 (CHK2), a protein that acts a tumor suppressor. CHK2 regulates cell division, and has the ability to prevent cells from dividing too rapidly or in an uncontrolled manner. When DNA undergoes a double-strand break, CHK2 is activated. Specifically, DNA damage … See more CHEK2 (Checkpoint kinase 2) is a tumor suppressor gene that encodes the protein CHK2, a serine-threonine kinase. CHK2 is involved in DNA repair, cell cycle arrest or apoptosis in response to DNA damage. Mutations to the … See more The CHEK2 gene is located on the long (q) arm of chromosome 22 at position 12.1. Its location on chromosome 22 stretches from See more The CHK2 protein plays a critical role in the DNA damage checkpoint.

WebDec 12, 2024 · However, although CHK2 kinase coded by the CHEK2 gene expedites the DDR signal, its function in activation of p53-dependent cell cycle arrest is dispensable. … WebAug 1, 2024 · TIM also has functions in DDR, including modulation of CHK1 and ATR downstream of single-strand DNA breaks, and activation of CHK2 via ATM modulation downstream of double strand breaks . Taken together, distinct circadian components are necessary to elicit canonical DDR for both single-strand and double-strand DNA breaks. WebCHEK2 produces a checkpoint kinase protein, activated in response to radiation and other agents that cause breaks in the DNA. CHK2 (or CHEK2) functions broadly comparable to ATM, has been implicated in some instances of LFS and is considered a low-penetrance breast cancer gene. react easy sort
