Ku70/Ku80 beta-barrel domain (IPR006164)

Short name: Ku70/Ku80_beta-barrel_dom

Overlapping homologous superfamilies

Domain relationships



The Ku heterodimer (composed of Ku70 and Ku80) 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 and Ku80 proteins that form a DNA binding heterodimer [PMID: 11493912].
