Gene Ontology Molecular Function
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.

BLM ortholog, Sgs1, prevents aberrant crossing-over by suppressing formation of multichromatid joint molecules.
Bloom's helicase (BLM) is thought to prevent crossing-over during DNA double-strand-break repair (DSBR) by disassembling double-Holliday junctions (dHJs) or by preventing their formation. We show that the Saccharomyces cerevisiae BLM ortholog, Sgs1, prevents aberrant crossing-over during meiosis by suppressing formation of joint molecules (JMs) comprising three and four interconnected duplexes. Sgs1 and procrossover factors, Msh5 and Mlh3, are antagonistic since ... [more]

| SGS1 MLH3 | Affinity Capture-Western 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. | Low | - | BioGRID | - | |
