RFA1

BUF2, FUN3, RPA1, RPA70, replication factor A subunit protein RFA1, L000000204, L000001620, YAR007C
Subunit of heterotrimeric Replication Protein A (RPA); RPA is a highly conserved single-stranded DNA binding protein involved in DNA replication, repair, and recombination; RPA protects against inappropriate telomere recombination, and upon telomere uncapping, prevents cell proliferation by a checkpoint-independent pathway; role in DNA catenation/decatenation pathway of chromosome disentangling; relocalizes to the cytosol in response to hypoxia

MGS1

ssDNA-dependent ATPase MGS1, YNL218W
Protein with DNA-dependent ATPase and ssDNA annealing activities; involved in maintenance of genome; interacts functionally with DNA polymerase delta; homolog of human Werner helicase interacting protein (WHIP); forms nuclear foci upon DNA replication stress

Dosage Lethality

A genetic interaction is inferred when over expression or increased dosage of one gene causes lethality in a strain that is mutated or deleted for another gene.

Publication

The product of Saccharomyces cerevisiae WHIP/MGS1, a gene related to replication factor C genes, interacts functionally with DNA polymerase delta.

Branzei D, Seki M, Onoda F, Enomoto T

The Saccharomyces cerevisiae gene WHIP/ MGS1 encodes a protein related to the subunits of Replication Factor C (RFC). We found that the RFC-like motifs in Whip/Mgs1 are essential for its function. Furthermore, by screening for synthetic dosage lethality, we have shown that overexpression of MGS1 causes lethality in combination with mutations in genes that encode replication proteins such as DNA ...

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.
