Figure 3.In vitro phosphorylation at Ser-440 and −467 by DNA-PKGST-tagged WRN fragment (239-499) as schematically represented was used. Purified GST or GST-tagged fragment with or without Ala substitution at Ser-440 and/or −467 was incubated with purified DNA-PKcs, Ku 70/86, and activated DNA in the presence of [γ-³²P]ATP. Phosphorylation was visualized (upper panel). An immunoblot with anti-GST antibody is shown (lower panel).
