Protein Structure
UniProt Annotation
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 (By similarity). {ECO:0000250}.
Subcellular Localization Nucleus {ECO:0000250}. Cytoplasm {ECO:0000250}. Note=Cytoplasmic in normal conditions. Translocates to the nucleus following DNA damage (By similarity). {ECO:0000250}.
