MOB2

YFL035C, YFL035C-A, L000003535, S000007658, S000002966, YFL034C-B
Activator of Cbk1p kinase; component of the RAM signaling network that regulates cellular polarity and morphogenesis; activation of Cbk1p facilitates the Ace2p-dependent daughter cell-specific transcription of genes involved in cell separation; similar to Mob1p
Saccharomyces cerevisiae (S288c)
PREY

ACE2

DNA-binding transcription factor ACE2, L000000020, YLR131C
Transcription factor required for septum destruction after cytokinesis; phosphorylation by Cbk1p blocks nuclear exit during M/G1 transition, causing localization to daughter cell nuclei, and also increases Ace2p activity; phosphorylation by Cdc28p and Pho85p prevents nuclear import during cell cycle phases other than cytokinesis; part of RAM network that regulates cellular polarity and morphogenesis; ACE2 has a paralog, SWI5, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)

Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

ACE2, CBK1, and BUD4 in budding and cell separation.

Voth WP, Olsen AE, Sbia M, Freedman KH, Stillman DJ

Mutations in the RAM network genes, including CBK1, MOB2, KIC1, HYM1, and TAO3, cause defects in bud site selection, asymmetric apical growth, and mating projections. Additionally, these mutants show altered colony morphology, cell separation defects, and reduced CTS1 expression, phenotypes also seen by mutating the Ace2 transcription factor. We show that an ACE2 multicopy plasmid suppresses the latter three defects ... [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.
