condensin subunit SMC2, L000001927, YFR031C
Subunit of the condensin complex; condensin reorganizes chromosomes during both mitosis and meiosis; essential SMC chromosomal ATPase family member that forms a subcomplex with Smc2p that has ATP-hydrolyzing and DNA-binding activity, but other condensin subunits are required for chromatin binding; required for clustering of tRNA genes at the nucleolus
Saccharomyces cerevisiae (S288c)


MGO1, SCF ubiquitin ligase subunit SKP1, CBF3D, L000001910, YDR328C
Evolutionarily conserved kinetochore protein; part of multiple protein complexes, including the SCF ubiquitin ligase complex, the CBF3 complex that binds centromeric DNA, and the RAVE complex that regulates assembly of the V-ATPase; protein abundance increases in response to DNA replication stress
Saccharomyces cerevisiae (S288c)

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.


Condensin function at centromere chromatin facilitates proper kinetochore tension and ensures correct mitotic segregation of sister chromatids.

The condensin complex is essential for sister chromatid segregation in eukaryotic mitosis. Nevertheless, in budding yeast, condensin mutations result in massive mis-segregation of chromosomes containing the nucleolar organizer, while other chromosomes, which also contain condensin binding sites, remain genetically stable. To investigate this phenomenon we analyzed the mechanism of the cell-cycle arrest elicited by condensin mutations. Under restrictive conditions, the ... [more]
