General annotation (Comments)

Function	May have a role in checkpoint signaling during mitosis By similarity. Enhances TP53-mediated transcriptional activation. Plays a role in the response to DNA damage.
Subunit structure	Interacts with IFI202A By similarity. Binds to the central domain of TP53/p53. May form homo-oligomers. Interacts with DCLRE1C. Interacts with histone H2AFX and this requires phosphorylation of H2AFX on 'Ser-139'. Interacts with histone H4 that has been dimethylated at 'Lys-20'. Has low affinity for histone H4 containing monomethylated 'Lys-20'. Does not bind histone H4 containing unmethylated or trimethylated 'Lys-20'. Has low affinity for histone H3 that has been dimethylated on 'Lys-79'. Has very low affinity for histone H3 that has been monomethylated on 'Lys-79' (in vitro). Does not bind unmethylated histone H3.
Subcellular location	Nucleus. Kinetochore. Note: Associated with kinetochores. Both nuclear and cytoplasmic in some cells. Recruited to sites of DNA damage, such as double stand breaks. Methylation of histone H4 at 'Lys-20' is required for efficient localization to double strand breaks. Ref.1 Ref.8 Ref.12 Ref.13 Ref.26
Post-translational modification	Asymmetrically dimethylated on Arg residues by PRMT1. Methylation is required for DNA binding. Ref.12 Ref.13 Phosphorylated at basal level in the absence of DNA damage. Hyper-phosphorylated in an ATM-dependent manner in response to DNA damage induced by ionizing radiation. Hyper-phosphorylated in an ATR-dependent manner in response to DNA damage induced by UV irradiation. Ref.8 Ref.7 Ref.11 Ref.14 Ref.15 Ref.16 Ref.17 Ref.18 Ref.19 Ref.20 Ref.21 Ref.22
Sequence similarities	Contains 2 BRCT domains.
