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].

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 amino terminal alpha/beta domain. This domain only makes a small contribution to the dimer interface. The domain comprises a six stranded beta sheet of the Rossman fold [1].

This family consists of several eukaryotic DNA double-strand break repair and V(D)J recombination protein XRCC4 sequences. In the non-homologous end joining pathway of DNA double-strand break repair, the ligation step is catalysed by a complex of XRCC4 and DNA ligase IV. It is thought that XRCC4 and ligase IV are essential for alignment-based gap filling, as well as for final ligation of the breaks [1]. This entry represents the N-terminal beta sandwich domain.
XLF (also called Cernunnos) is Xrcc4-like-factor, and interacts with the XRCC4-DNA ligase IV complex to promote DNA non-homologous end-joining. It directly interacts with the XRCC4-Ligase IV complex and siRNA-mediated down-regulation of XLF in human ...
XLF (also called Cernunnos) is Xrcc4-like-factor, and interacts with the XRCC4-DNA ligase IV complex to promote DNA non-homologous end-joining. It directly interacts with the XRCC4-Ligase IV complex and siRNA-mediated down-regulation of XLF in human cell lines leads to radio-sensitivity and impaired DNA non-homologous end-joining [1]. This family contains Nej1 (non-homologous end-joining factor) [2], and Lif1, ligase-interacting factor [3]. XLF forms one of the components of the NHEJ machinery for DNA non-homologous end-joining [4]. This entry represents the N-terminal beta sandwich domain of XLF.

The BRCT domain is found predominantly in proteins involved in cell cycle checkpoint functions responsive to DNA damage. The BRCT domain of XRCC1 forms a homodimer in the crystal structure. This suggests that pairs of BRCT domains associate as homo- or heterodimers. BRCT domains are often found as tandem-repeat pairs [2]. Structures of the BRCA1 BRCT domains revealed a basis for a widely utilised head-to-tail BRCT-BRCT oligomerisation mode [3]. This conserved tandem BRCT architecture facilitates formation of the canonical BRCT phospho-peptide interaction cleft at a groove between the BRCT domains. Disease associated missense and nonsense mutations in the BRCA1 BRCT domains disrupt peptide binding by directly occluding this peptide binding groove, or by disrupting key conserved BRCT core folding determinants [5].
