CRYSTAL STRUCTURE OF A XRCC4-DNA LIGASE IV COMPLEXCRYSTAL STRUCTURE OF A XRCC4-DNA LIGASE IV COMPLEX

Structural highlights

1ik9 is a 3 chain structure with sequence from Homo sapiens. The July 2004 RCSB PDB Molecule of the Month feature on DNA Ligase by David S. Goodsell is 10.2210/rcsb_pdb/mom_2004_7. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2.3Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

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.[1] [2] [3] [4]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
