Just before final end joining, the bound repair proteins must be released. However, the precise steps by which this happens is not known. The repair of DSB is an energy consuming event that requires DNA PK kinase activity as well (Malu et al. 2012, Hsu et al. 2002, Lee et al. 2004, Nick McElhinny et al. 2000).
