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)
PREY

SAE2

COM1, ssDNA endodeoxyribonuclease SAE2, L000002892, YGL175C
Endonuclease required for telomere elongation; also required for telomeric 5' C-rich strand resection; involved in processing hairpin DNA structures with MRX complex; involved in double-strand break repair; required for normal resistance to DNA-damaging agents; exists in form of inactive oligomers that are transiently released into smaller active units by a series of phosphorylations; DNA damage triggers removal of Sae2p ensuring that active Sae2p is present only transiently
Saccharomyces cerevisiae (S288c)

Phenotypic Suppression

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

Fragile DNA Motifs Trigger Mutagenesis at Distant Chromosomal Loci in Saccharomyces cerevisiae.

DNA sequences capable of adopting non-canonical secondary structures have been associated with gross-chromosomal rearrangements in humans and model organisms. Previously, we have shown that long inverted repeats that form hairpin and cruciform structures and triplex-forming GAA/TTC repeats induce the formation of double-strand breaks which trigger genome instability in yeast. In this study, we demonstrate that breakage at both inverted repeats ... [more]

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
