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
Saccharomyces cerevisiae (S288c)

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.

Mismatch repair and DNA polymerase ? proofreading prevent catastrophic accumulation of leading strand errors in cells expressing a cancer-associated DNA polymerase ? variant.

Bulock CR, Xing X, Shcherbakova PV

Substitutions in the exonuclease domain of DNA polymerase ? cause ultramutated human tumors. Yeast and mouse mimics of the most common variant, P286R, produce mutator effects far exceeding the effect of Pol? exonuclease deficiency. Yeast Pol?-P301R has increased DNA polymerase activity, which could underlie its high mutagenicity. We aimed to understand the impact of this increased activity on the strand-specific ... [more]
