POL2

DUN2, DNA polymerase epsilon catalytic subunit, L000001461, YNL262W
Catalytic subunit of DNA polymerase (II) epsilon; a chromosomal DNA replication polymerase that exhibits processivity and proofreading exonuclease activity; participates in leading-strand synthesis during DNA replication; also involved in DNA synthesis during DNA repair; interacts extensively with Mrc1p

POL3

CDC2, HPR6, TEX1, DNA-directed DNA polymerase delta POL3, L000000242, YDL102W
Catalytic subunit of DNA polymerase delta; required for chromosomal DNA replication during mitosis and meiosis, intragenic recombination, repair of double strand DNA breaks, and DNA replication during nucleotide excision repair (NER)
Saccharomyces cerevisiae (S288c)

Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

DNA polymerase ? proofreads errors made by DNA polymerase ?.

Bulock CR, Xing X, Shcherbakova PV

During eukaryotic replication, DNA polymerases ? (Pol?) and ? (Pol?) synthesize the leading and lagging strands, respectively. In a long-known contradiction to this model, defects in the fidelity of Pol? have a much weaker impact on mutagenesis than analogous Pol? defects. It has been previously proposed that Pol? contributes more to mutation avoidance because it proofreads mismatches created by Pol? ... [more]
