== Function == | |||
[https://www.uniprot.org/uniprot/POLK_HUMAN POLK_HUMAN] 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.<ref>PMID:10620008</ref> <ref>PMID:11024016</ref> <ref>PMID:12145297</ref> <ref>PMID:12444249</ref> <ref>PMID:12952891</ref> <ref>PMID:14630940</ref> <ref>PMID:15533436</ref> | |||
