EXO1

DHS1, Rad2 family nuclease EXO1, L000000505, L000003929, YOR033C
5'-3' exonuclease and flap-endonuclease; involved in recombination, double-strand break repair, MMS2 error-free branch of the post replication (PRR) pathway and DNA mismatch repair; role in telomere maintenance; member of the Rad2p nuclease family, with conserved N and I nuclease domains; relative distribution to the nucleus increases upon DNA replication stress; EXO1 has a paralog, DIN7, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)
PREY

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.

Exonuclease 1 preferentially repairs mismatches generated by DNA polymerase α

Liberti SE, Larrea AA, Kunkel TA

The Saccharomyces cerevisiae EXO1 gene encodes a 5' exonuclease that participates in mismatch repair (MMR) of DNA replication errors. Deleting EXO1 was previously shown to increase mutation rates to a greater extent when combined with a mutator variant (pol3-L612M) of the lagging strand replicase, DNA polymerase δ (Pol δ), than when combined with a mutator variant (pol2-M644G) of the leading ...

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.
