Description
CHEK2 is the official symbol for the human gene Checkpoint kinase 2. CHEK2 is located on the the long (q) arm of chromosome 22. CHEK2 is tumor suppressor gene that encodes the protein CHK2, a serine threonine kinase. CHK2 operates in an intricate network of proteins to elicit DNA repair, cell cycle arrest or apoptosis in response to DNA damage. Mutations to the CHEK2 gene have been linked to a wide range of cancers including breast cancer.
