WebMar 1, 2007 · Checkpoint kinase 1 (Chk1) is an important regulator of genome maintenance by the HRR system. Chk1 interacts with Rad51; Chk1-depleted cells fail to form Rad51 nuclear repair foci after hydroxyurea-induced DSBs and inhibition of DNA replication ( 8 ). Chk1 can also be activated by a number of replication inhibitors, including etoposide ( 9 … WebApr 24, 2024 · However, pretreatment with an autophagy inhibitor offsets the effects of MG132 on CHK1 and RAD51 levels. These findings imply that p62 accumulation in the nucleus in response to autophagy inhibition promotes proteasome-mediated CHK1 and RAD51 protein instability.
