TUB3

alpha-tubulin TUB3, L000002389, YML124C
Alpha-tubulin; associates with beta-tubulin (Tub2p) to form tubulin dimer, which polymerizes to form microtubules; expressed at lower level than Tub1p; TUB3 has a paralog, TUB1, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)
PREY

IRA2

CCS1, GLC4, Ras GTPase activating protein IRA2, L000000874, YOL081W
GTPase-activating protein; negatively regulates RAS by converting it from the GTP- to the GDP-bound inactive form, required for reducing cAMP levels under nutrient limiting conditions; IRA2 has a paralog, IRA1, that arose from the whole genome duplication; defects in human homolog NF1 are associated with neurofibromatosis
Saccharomyces cerevisiae (S288c)

Positive Genetic

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a less severe fitness defect than expected under a given condition. This term is reserved for high or low throughput studies with scores.

Tubulin isotypes optimize distinct spindle positioning mechanisms during yeast mitosis.

Nsamba ET, Bera A, Costanzo M, Boone C, Gupta ML

Microtubules are dynamic cytoskeleton filaments that are essential for a wide range of cellular processes. They are polymerized from tubulin, a heterodimer of ?- and ?-subunits. Most eukaryotic organisms express multiple isotypes of ?- and ?-tubulin, yet their functional relevance in any organism remains largely obscure. The two ?-tubulin isotypes in budding yeast, Tub1 and Tub3, are proposed to be ... [more]
