CHEK2 [SEP] chromosome
CHEK2
CHEK2 (Checkpoint kinase 2) is a tumor suppressor gene that encodes the protein CHK2, a serine-threonine kinase. CHK2 is involved in 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.
Gene location.
The CHEK2 gene is located on the long (q) arm of chromosome 22 at position 12.1. Its location on chromosome 22 stretches from base pair 28,687,742 to base pair 28,741,904.

to deputy director in 2007. In May 2010, he was appointed director, succeeding Allan Bradley.
Stratton's research interests are in the area of genetics of cancer. In 1994 he assembled a research group that localised BRCA2, a major breast cancer susceptibility gene that repairs chromosomal damage, to chromosome 13. The following year his team identified the gene and, in doing so generated a megabase segment of high-quality human genome sequence. His subsequent work has involved the identification of more moderate cancer susceptibility genes such as CHEK2
