WebWe show that Chk1 is associated with chromatin in cycling cells and that the chromatin-associated Chk1 is phosphorylated in the absence of exogenous DNA damage. The UV-induced Ser-345-phosphorylated forms of Chk1 that appear minutes after treatment are predominantly associated with chromatin. WebThis indicated that Chk1-dependent phosphorylation (p-Chk1 Ser345) of Cdc25C Ser216 is required, which, in turn, acts to sustain G2/M arrest in both breast cancer cell lines.
