Autophosphorylated Residues Involved in the Regulation of Human Chk2 In Vitro

Human checkpoint kinase 2 is a major actor in checkpoint activation through phosphorylation by ataxia telangiectasia mutated in response to DNA double-strand breaks. In the absence of de novo DNA damage, its autoactivation, reported in the event of increased Cds1/checkpoint kinase 2 (Chk2) expressio...
