[[1ik9]] is a 3 chain structure with sequence from [http://en.wikipedia.org/wiki/Homo_sapiens Homo sapiens]. The July 2004 RCSB PDB [http://pdb.rcsb.org/pdb/static.do?p=education_discussion/molecule_of_the_month/index.html Molecule of the Month] feature on ''DNA Ligase'' by David S. Goodsell is [http://dx.doi.org/10.2210/rcsb_pdb/mom_2004_7 10.2210/rcsb_pdb/mom_2004_7]. Full crystallographic information is available from [http://oca.weizmann.ac.il/oca-bin/ocashort?id=1IK9 OCA].

== Function ==
 +
[https://www.uniprot.org/uniprot/XRCC4_HUMAN XRCC4_HUMAN] 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.<ref>PMID:8548796</ref> <ref>PMID:10854421</ref> <ref>PMID:10757784</ref> <ref>PMID:16412978</ref>
