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.
