DNA-PKcs and Ku are essential components of the complex that catalyzes non-homologous end joining (NHEJ) of DNA double-strand breaks (DSBs). Ku, a heterodimeric protein, binds to DNA ends and facilitates recruitment of the catalytic subunit, DNA-PKcs. We have investigated the effect of DNA strand orientation and sequence bias on the activation of DNA-PK. In(More)
DNA-dependent protein kinase (DNA-PK) is an essential component of the nonhomologous end joining pathway (NHEJ), responsible for the repair of DNA double-strand breaks. Ku binds a DSB and recruits the catalytic subunit, DNA-PKcs, where it is activated once the kinase is bound to the DSB. The precise mechanism by which DNA activates DNA-PK remains unknown.(More)
