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.

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.
