Description

DNA polymerase epsilon catalytic subunit (also known as POL2) is a catalytic subunit of DNA polymerase epsilon, which is a a high-fidelity polymerase participating in chromosomal DNA replication [PMID: 24292646]. It contains both polymerase and 3'-5'-exonuclease domains [PMID: 24292646]. Its 3'-5'-exonuclease domain ensures a particularly low error rate [PMID: 24583393]. POL2 also plays a role in DNA repair and is linked to cancer [PMID: 24583393]. Its structure has been solved [PMID: 24733111].
