General annotation (Comments)

Function	Repair polymerase that plays a key role in base-excision repair. Has 5'-deoxyribose-5-phosphate lyase (dRP lyase) activity that removes the 5' sugar phosphate and also acts as a DNA polymerase that adds one nucleotide to the 3' end of the arising single-nucleotide gap. Conducts 'gap-filling' DNA synthesis in a stepwise distributive fashion rather than in a processive fashion as for other DNA polymerases. Ref.11 Ref.12 Ref.13 Ref.16
Catalytic activity	Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).
Cofactor	Binds 2 magnesium ions per subunit By similarity.
Subunit structure	Monomer. Interacts with APEX1, HUWE1/ARF-BP1, STUB1/CHIP and USP47. Ref.11 Ref.16
Subcellular location	Nucleus. Cytoplasm. Note: Cytoplasmic in normal conditions. Translocates to the nucleus following DNA damage. Ref.15 Ref.16
Domain	Residues 239-252 form a flexible loop which appears to affect the polymerase fidelity By similarity.
Post-translational modification	Methylation by PRMT6 stimulates the polymerase activity by enhancing DNA binding and processivity. Ubiquitinated at Lys-41, Lys-61 and Lys-81: monoubiquitinated by HUWE1/ARF-BP1. Monoubiquitinated protein is then the target of STUB1/CHIP, which catalyzes polyubiquitination from monoubiquitin, leading to degradation by the proteasome. USP47 mediates the deubiquitination of monoubiquitinated protein, preventing polyubiquitination by STUB1/CHIP and its subsequent degradation. Ref.15 Ref.16
Sequence similarities	Belongs to the DNA polymerase type-X family.
