NGS1, RAD58, XRS4, MRX complex nuclease subunit, L000004732, L000001149, L000004275, YMR224C
Nuclease subunit of the MRX complex with Rad50p and Xrs2p; complex functions in repair of DNA double-strand breaks and in telomere stability; Mre11p associates with Ser/Thr-rich ORFs in premeiotic phase; nuclease activity required for MRX function; widely conserved; forms nuclear foci upon DNA replication stress

Phenotypic Enhancement

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

Cohesin complex oligomerization maintains end-tethering at DNA double-strand breaks.

DNA double-strand breaks (DSBs) must be repaired to ensure genome stability. Crucially, DSB-ends must be kept together for timely repair. In Saccharomyces cerevisiae, two pathways mediate DSB end-tethering. One employs the Mre11-Rad50-Xrs2 (MRX) complex to physically bridge DSB-ends. Another requires the conversion of DSB-ends into single-strand DNA (ssDNA) by Exo1, but the bridging proteins are unknown. We uncover that cohesin, ... [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.
