| 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. {ECO:0000269|PubMed:11805079, ECO:0000269|PubMed:21362556, ECO:0000269|PubMed:9207062, ECO:0000269|PubMed:9572863}.
