NCBI Protein Information
DNA ligase IV
NCBI Summary
Encodes the Arabidopsis orthologue of the yeast and mammalian DNA ligase IV. Involved in the repair of DNA damage but, unlike in yeast, not required for T-DNA integration. Interacts with the Arabidopsis homologue of XRCC4.

UniProt Comments
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. May be involved for T-DNA integration even if not absolutely required. Seems to be dispensable under normal growth conditions.
