TUB1

alpha-tubulin TUB1, L000002387, YML085C
Alpha-tubulin; associates with beta-tubulin (Tub2p) to form tubulin dimer, which polymerizes to form microtubules; relative distribution to nuclear foci increases upon DNA replication stress; TUB1 has a paralog, TUB3, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)
PREY

RBL2

L000002910, YOR265W
Protein involved in microtubule morphogenesis; required for protection from excess free beta-tubulin; proposed to be involved the folding of beta-tubulin; similar to mouse beta-tubulin cofactor A; protein abundance increases in response to DNA replication stress

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]
