Autophosphorylation of DNA-PKcs (PRKDC) is required for NHEJ in vivo, especially for endonucleolytic processing of DNA double strand break ends, which makes them suitable for ligation (Chan et al, 2002; Ding et al, 2003). In vivo, PRKDC autophosphorylates at threonine residues T2609, T2638 and T2647, and serine residue S2612 (Douglas et al. 2002).
