| TUS1Gene Symbol: TUS1 Description: Rho family guanine nucleotide exchange factor TUS1 Alias: SOP10, Rho family guanine nucleotide exchange factor TUS1 Species: Saccharomyces cerevisiae S288c Yoshida S, Kono K, Lowery D, Bartolini S, Yaffe M, Ohya Y, et al. Polo-like kinase Cdc5 controls the local activation of Rho1 to promote cytokinesis. Science. 2006;313:108-11 pubmed ..This role of Cdc5 (Polo-like kinase) in regulating Rho1 is likely to be relevant to cytokinesis and asymmetric cell division in other organisms. ..

Mol Biol Cell. 2008;19:1763-71 pubmed publisher ..We propose that Cln2p/Cdc28p-dependent phosphorylation of Tus1p is required for appropriate temporal and spatial activation of Rho1p at the G1/S transition. .. Yoshida S, Bartolini S, Pellman D. Mechanisms for concentrating Rho1 during cytokinesis. Genes Dev. 2009;23:810-23 pubmed publisher ..These findings comprehensively define the targeting mechanisms of Rho1 essential for cytokinesis in yeast, and are likely to be relevant to cytokinesis in other organisms. ..
