BAIT

POL31

HUS2, HYS2, SDP5, L000002981, YJR006W
Subunit of DNA polymerase delta (polymerase III); essential for cell viability; involved in DNA replication and DNA repair; forms a complex with Rev3p, Rev7p and Pol32p; relocalizes to the cytosol in response to hypoxia
Saccharomyces cerevisiae (S288c)
PREY

DIA2

YOR29-31, DNA-binding SCF ubiquitin ligase subunit DIA2, YOR080W
Origin-binding F-box protein; forms SCF ubiquitin ligase complex with Skp1p and Cdc53p; functions in ubiquitylation of silent chromatin structural protein Sir4p; required to target Cdc6p for destruction during G1 phase; required for deactivation of Rad53 checkpoint kinase, completion of DNA replication during recovery from DNA damage, assembly of RSC complex, RSC-mediated transcription regulation, and nucleosome positioning; involved in invasive and pseudohyphal growth
UPS Project
Saccharomyces cerevisiae (S288c)

Affinity Capture-Western

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.

Yra1 is required for S phase entry and affects Dia2 binding to replication origins.

Swaminathan S, Kile AC, MacDonald EM, Koepp DM

The Saccharomyces cerevisiae F-box protein Dia2 is important for DNA replication and genomic stability. Using an affinity approach, we identified Yra1, a transcription-coupled mRNA export protein, as a Dia2 interaction partner. We find that yra1 mutants are sensitive to DIA2 expression levels. Like Dia2, Yra1 associates with chromatin and binds replication origins, suggesting that they may function together in DNA ... [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.
