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.

Srs2 overexpression reveals a helicase-independent role at replication forks that requires diverse cell functions.
Srs2 is a 3'-5' DNA helicase that regulates many aspects of DNA metabolism in Saccharomyces cerevisiae. It is best known for its ability to counteract homologous recombination by dismantling Rad51 filaments, but is also involved in checkpoint activation, adaptation and recovery, and in resolution of late recombination intermediates. To further address its biological roles and uncover new genetic interactions, we ... [more]

Ontology Terms
- phenotype: inviable (APO:0000112)
- phenotype: colony size (APO:0000063)
Additional Notes
- High Throughput: Three synthetic dosage lethality screens were carried out to identify genes required for cell viability upon overexpression of SRS2 and/or its helicase mutants srs2-K41A and srs2-K41R.
- Low Throughput: Selected SDL interactions were verified by transforming the overexpression plasmids into each strain and assessing the growth of the transformants using spot-assays.

| NFI1 SRS2 | Biochemical Activity Biochemical Activity An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation. | Low | - | BioGRID | 665509 | |
