  Domain Name: KU
Ku-core domain; includes the central DNA-binding beta-barrels, polypeptide rings, and the C-terminal arm of Ku proteins. The Ku protein consists of two tightly associated homologous subunits, Ku70 and Ku80, and was originally identified as an autoantigen recognized by the sera of patients with an autoimmunity disease. In eukaryotes, the Ku heterodimer contributes to genomic integrity through its ability to bind DNA double-strand breaks and facilitate repair by non-homologous end-joining. The bacterial Ku homologs does not contain the conserved N-terminal extension that is present in the eukaryotic Ku protein.
No pairwise interactions are available for this conserved domain.

Tips:
 If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position.

 The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs.

 Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below.
