Protein Structure
UniProt Annotation
Function Involved in DNA non-homologous end joining (NHEJ) required for double-strand break repair and V(D)J recombination. Binds to DNA and to DNA ligase IV (LIG4). The LIG4-XRCC4 complex is responsible for the NHEJ ligation step, and XRCC4 enhances the joining activity of LIG4. Binding of the LIG4-XRCC4 complex to DNA ends is dependent on the assembly of the DNA-dependent protein kinase complex DNA-PK to these DNA ends. {ECO:0000269PubMed:10757784, ECO:0000269PubMed:10854421, ECO:0000269PubMed:16412978, ECO:0000269PubMed:8548796}.
