The use of cell division cycle mutants to investigate the control of microtubule distribution in the fission yeast Schizosaccharomyces pombe.
The unique properties of various cell division cycle mutants are used to investigate further the function of these different microtubule arrays and their temporal and positional control. Expand
Localization of F-actin through the cell division cycle of Schizosaccharomyces pombe.
Etude de la localisation de the F-actine durant les etapes du cycle cellulaire de S. pombe montrant qu'elle coincide avec the deposition of the paroi cellulaires and qu'elles disparait faisant place a un anneau equatorial d'actine a la mitose. Expand
Growth Polarity and Cytokinesis in Fission Yeast: The Role of the Cytoskeleton
The distribution of F-actin in the fission yeast Schizosaccharomyces pombe was investigated by fluorescence microscopy using rhodamine-conjugated phalloidin and a system of cytoplasmic microtubules extending between the cell ends was revealed. Expand
The fission yeast cdc2/cdc13/suc1 protein kinase: Regulation of catalytic activity and nuclear localization
Observations suggest that the cdc13+-encoded cyclin acts to regulate both the catalytic properties and the localization of the protein kinase of which it is a subunit. Expand
Two type V myosins with non-overlapping functions in the fission yeast Schizosaccharomyces pombe: Myo52 is concerned with growth polarity and cytokinesis, Myo51 is a component of the cytokinetic…
The fission yeast genome project has identified five myosin genes and cells deleted for myo51(+) show normal morphology and growth rates whereas deletion of myo52(+) results in a partial loss of cell polarity, slow growth and cytokinetic defects. Expand
Type II myosin involved in cytokinesis in the fission yeast, Schizosaccharomyces pombe.
The results suggest that a contractile actin-myosin based cytokinetic mechanism appeared early in the evolution of eukaryotic cells and further emphasise the utility of fission yeast as a model organism in which to study the molecular and cellular basis of cytokinesis. Expand
Endocytosis in fission yeast is spatially associated with the actin cytoskeleton during polarised cell growth and cytokinesis
It is concluded that endocytosis in fission yeast has two distinct components, both of which are actin-based, but which are mechanistically distinct, as well as being spatially and temporally separated in the S. pombe cell cycle. Expand

Adding of Latrunculin A, which prevents spindle rotation, delays the separation of sister chromatids and anaphase promoting complex-mediated destruction of spindle-associated Securin and Cyclin B is shown. Expand
A MAP kinase-dependent actin checkpoint ensures proper spindle orientation in fission yeast
A distinct mitotic checkpoint in the fission yeast, Schizosaccharomyces pombe, is described that monitors the integrity of the actin cytoskeleton and delays sister chromatid separation, spindle elongation and cytokinesis until spindle poles have been properly oriented. Expand
Dynamin‐Dependent Biogenesis, Cell Cycle Regulation and Mitochondrial Association of Peroxisomes in Fission Yeast
It is concluded thatPeroxisomes are present in fission yeast and that Dnm1 and Vps1 act redundantly in peroxisome biogenesis, which is under cell cycle control. Expand
