Microtubule Interactions with the Cell Cortex Causing Nuclear Movements in Saccharomyces cerevisiae

During mitosis in budding yeast the nucleus first moves to the mother-bud neck and then into the neck. Both movements depend on interactions of cytoplasmic microtubules with the cortex. We investigated the mechanism of these movements in living cells using video analysis of GFP-labeled microtubules in wild-type cells and in EB1 and Arp1 mutants, which are defective in the first and second steps...

Effect of microtubule-associated protein MHP1 on microtubule assembly and cell cycle progression in Saccharomyces cerevisiae.

Microtubule-associated proteins (MAPs) promote the assembly of microtubules from purified tubulin in vitro. In order to establish a model system for the investigation of the role of MAPs in microtubule assembly in vivo, we have generated Saccharomyces cerevisiae strains that permit the modulation of the expression levels of MHP1 (MAP-Homologous Protein 1) and of the alpha and beta-tubulin genes...

Bni1p regulates microtubule-dependent nuclear migration through the actin cytoskeleton in Saccharomyces cerevisiae.

The RHO1 gene encodes a yeast homolog of the mammalian RhoA protein. Rho1p is localized to the growth sites and is required for bud formation. We have recently shown that Bni1p is one of the potential downstream target molecules of Rho1p. The BNI1 gene is implicated in cytokinesis and the establishment of cell polarity in Saccharomyces cerevisiae but is not essential for cell viability. In this...

Subunit Interactions within the Saccharomyces cerevisiae DNA

Saccharomyces cerevisiae DNA polymerase epsilon (pol e) is essential for chromosomal replication. A major form of pol e purified from yeast consists of at least four subunits: Pol2p, Dpb2p, Dpb3p, and Dpb4p. We have investigated the protein/protein interactions between these polypeptides by using expression of individual subunits in baculovirus-infected Sf9 insect cells and by using the yeast t...

Interactions between Mad1p and the nuclear transport machinery in the yeast Saccharomyces cerevisiae.

In addition to its role in nucleocytoplasmic transport, the nuclear pore complex (NPC) acts as a docking site for proteins whose apparent primary cellular functions are unrelated to nuclear transport, including Mad1p and Mad2p, two proteins of the spindle assembly checkpoint (SAC) machinery. To understand this relationship, we have mapped domains of yeast Saccharomyces cerevisiae Mad1p that int...
