Description: XRCC4 (X-ray repair cross-complementing protein 4) is involved in DNA nonhomologous end joining (NHEJ) required for double-strand break repair and V(D)J recombination. XRCC4 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. XRCC4 is a homodimer and homotetramer in solution. The homodimer associates with LIG4, and the LIG4-XRCC4 complex associates in a DNA-dependent manner with the DNA-PK complex formed by the Ku p70/p86 dimer (G22P1/G22P2) and PRKDC. XRCC4 seems to interact directly with PRKDC but not with the Ku p70/86 dimer. It interacts with XLF/Cernunnos. Interacts with APTX and APLF. Sumoylation at Lys-210 is required for nuclear localization and recombination efficiency. It has no effect on ubiquitination.
