Cell-type-specific role of CHK2 in mediating DNA damage

WebApr 4, 2012 · ATR and CHK1 are both essential for cellular viability, which implies that the encoded proteins are required for normal cell proliferation. 7, 8 Interestingly, activation of the G 2 /M checkpoint appears to be a nonessential function of Chk1, as a phosphorylation site mutant of Chk1 defective for this activity is nonetheless able to support ... Chk1 has a central role in coordinating the DNA damage response and therefore is an area of great interest in oncology and the development of cancer therapeutics. Initially Chk1 was thought to function as a tumor suppressor due to the regulatory role it serves amongst cells with DNA damage.
