Protein
DNA repair protein xrcc4
Organism
Dictyostelium discoideum
Function
May be 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 (By similarity).
Similarity
Belongs to the XRCC4 family.
