Activated ATM hyper-phosphorylates TP53BP1 (53BP1) at multiple residues in response to DNA damage (Fernandez-Capetillo et al. 2002, Ward et al. 2003, Jowsey et al. 2007). Phosphorylation of TP53BP1 serine residues S25 and S1778 is important for the retention of TP53BP1 at DNA double-strand break (DSB) sites (Kang et al. 2009).
