Background Information

Chk2(Checkpoint kinase 2) is also named as CDS1, CHEK2, RAD53 and belongs to the CHK2 subfamily. It is a protein kinase that is activated in response to DNA damage and involved in cell cycle arrest. It also mediates the induction of senescence in fibroblasts, but is dispensable for the induction of telomere dysfunction checkpoints at the stem and progenitor cell level(PMID:20577265). This protein can exsit as a dimer (PMID:19782031). Active forms of CHEK2 devoid of phosphorylation at Thr-68 can form unstable dimers(PMID:12386164). Defects in CHEK2 is a cause of susceptibility to breast cancer (BC)(PMID:21618645). It has 12 isoforms produced by alternative splicing.
