Protein attributes

Sequence length	633 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Corrects defective DNA strand-break repair and sister chromatid exchange following treatment with ionizing radiation and alkylating agents.
Subunit structure	Homodimer. Interacts with polynucleotide kinase (PNK), DNA polymerase-beta (POLB) and DNA ligase III (LIG3). Interacts with APTX and APLF. Interacts with APEX1; the interaction is induced by SIRT1 and increases with the acetylated form of APEX1. Ref.6 Ref.7 Ref.9 Ref.10 Ref.13 Ref.14 Ref.15 Ref.18
Subcellular location	Nucleus. Note: Accumulates at sites of DNA damage. Ref.15
Post-translational modification	Phosphorylation of Ser-371 causes dimer dissociation. Phosphorylation by CK2 promotes interaction with APTX and APLF. Sumoylated. Ref.11
Polymorphism	Carriers of the polymorphic Gln-399 allele may be at greater risk for tobacco- and age-related DNA damage.
Sequence similarities	Contains 2 BRCT domains.
