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

BUB3

PAC9, L000000198, YOR026W
Kinetochore checkpoint WD40 repeat protein; localizes to kinetochores during prophase and metaphase, delays anaphase in the presence of unattached kinetochores; forms complexes with Mad1p-Bub1p and with Cdc20p, binds Mad2p and Mad3p

Negative Genetic

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.

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]
