Chk2 is a protein kinase involved in cell cycle arrest in response to DNA damage. CHK2 is activated through phosphorylation by ATM and ATR at T68. Activated CHK2 phosphorylates and inhibits CDC25 a dual-specificity phosphatase required for progression through the cell cycle. CHK2 further causes cell cycle earrest through activation of a DNA repair protein BRCA1 and apoptosis factor PML. The role of CHK2 in the development of cancer is in a primarily tumour suppressor role through causing cell cycle arrest. It has been observed that inhibition of CHK2 through mutations in the regulatory FHA domain has been observed in low frequency in osteosarcomas and cancers of the ovary, lung and vulva. Another mutation, "1100delC" has been commonly found in breast cancers.
