Ku70/Ku80 C-terminal arm (IPR005160)

Short name: Ku_C

Overlapping homologous superfamilies

Domain relationships



The Ku heterodimer (composed of Ku70 P12956 and Ku80 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 C-terminal arm. This alpha helical region embraces the beta-barrel domain IPR006164 of the opposite subunit [PMID: 11493912].
