Kinase-independent function of checkpoint kinase 1 (Chk1) in the replication of damaged DNA
(National Academy of Sciences, 2012-05)
The checkpoint kinases Chk1 and ATR are broadly known for their role in the response to the accumulation of damaged DNA. Because Chk1 activation requires its phosphorylation by ATR, it is expected that ATR or Chk1 ...
p21 differentially regulates DNA replication and DNA-repair-associated processes after UV irradiation
(Company of Biologists, 2008-09)
Although p21 upregulation is required to block cell-cycle progression following many types of genotoxic insult, UV irradiation triggers p21 proteolysis. The significance of the increased p21 turnover is unclear and might ...
