The Ku heterodimer (composed of Ku70 Swiss:P12956 and Ku80 Swiss:P13010) contributes to genomic integrity through its ability to bind DNA double-strand breaks and facilitate repair by the non-homologous end-joining pathway. This is the central DNA-binding beta-barrel domain. This domain is found in both the Ku70 Swiss:P12956 and Ku80 Swiss:P13010 proteins that form a DNA binding heterodimer [1].	Domain
