质量标准:【产品介绍】Chk2 is a cell cycle checkpoint regulator
and putative tumor suppressor. It contains a
forkhead-associated protein interaction domain essential
for activation in response to DNA damage and is
rapidly phosphorylated in response to replication blocks
and DNA damage. When activated, Chk2 is known to
inhibit CDC25C phosphatase, preventing entry into
mitosis, and has been shown to stabilize the
tumor suppressor protein p53, leading to cell cycle
arrest in G1. In addition, this protein interacts with
and phosphorylates BRCA1, allowing BRCA1 to restore
survival after DNA damage. Mutations in Chk2 have
been linked with Li-Fraumeni syndrome, a highly
penetrant familial cancer phenotype usually associated
with inherited mutations in TP53. Also, mutations in
this protein are thought to confer a predisposition
to sarcomas, breast cancer, and brain tumors (1).
