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)
PREY

MSH3

mismatch repair protein MSH3, L000001191, YCR092C
Mismatch repair protein; forms dimers with Msh2p that mediate repair of insertion or deletion mutations and removal of nonhomologous DNA ends, contains a PCNA (Pol30p) binding motif required for genome stability
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-independent tandem repeat sequence instability resulting from ribonucleotide incorporation by DNA polymerase É›

Clark AB, Lujan SA, Kissling GE, Kunkel TA

During DNA synthesis in vitro using dNTP and rNTP concentrations present in vivo, yeast replicative DNA polymerases α, δ and ɛ (Pols α, δ and ɛ) stably incorporate rNTPs into DNA. rNTPs are also incorporated during replication in vivo, and they are repaired in an RNase H2-dependent manner. In strains encoding a mutator allele of Pol ɛ (pol2-M644G), failure to ... [more]

Synthetic Lethality
Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.
