| Function |
DNA polymerase specifically involved in DNA repair. Plays an important role in translesion synthesis, where the normal high-fidelity DNA polymerases cannot proceed and DNA synthesis stalls. Depending on the context, it inserts the correct base, but causes frequent base transitions, transversions and frameshifts. Lacks 3'-5' proofreading exonuclease activity. Forms a Schiff base with 5'-deoxyribose phosphate at abasic sites, but does not have lyase activity. {ECO:0000269|PubMed:10620008, ECO:0000269|PubMed:11024016, ECO:0000269|PubMed:12145297, ECO:0000269|PubMed:12444249, ECO:0000269|PubMed:12952891, ECO:0000269|PubMed:14630940, ECO:0000269|PubMed:15533436}.
