. "The Ku heterodimer (composed of Ku70 Swiss:P12956 and Ku80Swiss: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 amino terminal alpha/beta domain. This domain only makes a small contribution to the dimer interface." . "Ku_N" . "Ku70/Ku80 N-terminal alpha/beta domain" . "Bateman A" .
