Name DNA ligase 4
Synonyms
  1. DNA ligase IV
  2. Polydeoxyribonucleotide synthase [ATP] 4
Gene Name LIG4
Protein Type Enzyme
Biological Properties
General Function Involved in DNA ligase (ATP) activity
Specific Function Efficiently joins single-strand breaks in a double-stranded polydeoxynucleotide in an ATP-dependent reaction. Involved in DNA non-homologous end joining (NHEJ) required for double-strand break repair and V(D)J recombination. 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.
Pathways
  • Non-homologous end-joining
Reactions
Adenosine triphosphate + (deoxyribonucleotide)(n) + (deoxyribonucleotide)(m) → Adenosine monophosphate + Pyrophosphate + (deoxyribonucleotide)(n+m) details
