TUB2

ARM10, SHE8, beta-tubulin, L000002388, YFL037W
Beta-tubulin; associates with alpha-tubulin (Tub1p and Tub3p) to form tubulin dimer, which polymerizes to form microtubules; mutation in human ortholog is associated with congenital fibrosis of the extraocular muscles (CFEOM) with polymicrogyria
Saccharomyces cerevisiae (S288c)
PREY

IPL1

PAC15, aurora kinase, L000000871, YPL209C
Aurora kinase of conserved chromosomal passenger complex; mediates release on mono-oriented kinetochores from microtubules in meiosis I, also release of kinetochores from cluster at SPBs at meiosis exit; helps maintain condensed chromosomes during anaphase, early telophase; required for SPB cohesion and prevention of multipolar spindle formation; Iocalizes to nuclear foci that diffuse upon DNA replication stress; required for inhibition of karyopherin Pse1p upon SAC arrest

Saccharomyces cerevisiae (S288c)

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.

Interphase Microtubules Safeguard Mitotic Progression by Suppressing an Aurora B-Dependent Arrest Induced by DNA Replication Stress.

Laflamme G, Sim S, Leary A, Pascariu M, Vogel J, D'Amours D

The segregation of chromosomes is a critical step during cell division. This process is driven by the elongation of spindle microtubules and is tightly regulated by checkpoint mechanisms. It is unknown whether microtubules affect checkpoint responses as passive contributors or active regulators of the process. We show here that interphase microtubules are essential to temporally restrict the effects of DNA ... [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.
