84-1168-33　CHK2 (Serine/Threonine-protein Kinase Chk2, Cds1, CHEK2, RAD53) 100ug　C4201-05H

特徴

• CHK2, a protein kinase that is activated in response to DNA damage, is involved in cell cycle arrest.Mapped on 22q12.1, CHK2 has a potential regulatory region rich in SQ and TQ aa pairs.
• It regulates BRCA1 function after DNA damage by phosphorylating serine-988 of BRCA11.
• Additionally, CHK2 can be modified by phosphorylation and activated in response to ionizing radiation, and can be also modified in response to hydroxyurea treatment.
• Furthermore, oligomerization of CHEK2 increases the efficiency of transautophosphorylation, resulting in the release of active CHEK2 monomers that proceed to enforce checkpoint control in irradiated cells.
• Morever, CHK2 is a tumor suppressor gene conferring predisposition to sarcoma, breast cancer, and brain tumors, and that their observations provided a link between the central role of p53 inactivation in human cancer and the well-defined G2 checkpoint in yeast.
• There is a wide expression of small amounts of CHK2 mRNA with larger amounts in human testis, spleen, colon, and peripheral blood leukocytes.
