DNA polymerase zeta catalytic subunit

UniProtKB accession:  P14284

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Nonessential DNA polymerase. Required for DNA damage induced mutagenesis. Involved in DNA repair, mitochondrial DNA repair and translesion synthesis. Translesion synthesis in S.cerevisiae may use a specialized DNA polymerase that is not required for other DNA replicative processes. Has a role in the bypass of abasic (AP) sites. Highly inefficient in incorporating nucleotides opposite the AP site, but efficiently extends from nucleotides, particularly an A, inserted opposite the lesion.
