Analysis of the S. pombe Meiotic Proteome Reveals a Switch from Anabolic to Catabolic Processes and Extensive Post-transcriptional Regulation

Viesturs Simanis, Andrea Krapp, Romain Hamelin, Diego Chiappe, Florence Armand, Lucien Fabrice Krapp, Marc Moniatte, Elena Cano

Meiotic progression in S. pombe is regulated by stage-specific gene expression and translation, changes in RNA stability, expression of anti-sense transcripts, and targeted proteolysis of regulatory proteins. We have used SILAC labeling to examine the rela ...

An Extended, Boolean Model of the Septation Initiation Network in S-pombe Provides Insights into Its Regulation

Viesturs Simanis, Andrea Krapp, Elena Cano, Anastasia Chasapi, Ioannis Xenarios

Cytokinesis in fission yeast is controlled by the Septation Initiation Network (SIN), a protein kinase signaling network using the spindle pole body as scaffold. In order to describe the qualitative behavior of the system and predict unknown mutant behavio ...

Noninvasive characterization of the fission yeast cell cycle by monitoring dry mass with digital holographic microscopy

Pierre Magistretti, Christian Depeursinge, Tristan Colomb, Benjamin Rappaz, Viesturs Simanis, Pierre Marquet, Jonas Kühn, Elena Cano

Digital holography microscopy (DHM) is an optical technique which provides phase images yielding quantitative information about cell structure and cellular dynamics. Furthermore, the quantitative phase images allow the derivation of other parameters, inclu ...

Functional differentiation of tbf1 orthologues in fission and budding yeasts

Viesturs Simanis, Elena Cano

In Saccharomyces cerevisiae, TBF1, an essential gene, influences telomere function but also has other roles in the global regulation of transcription. We have identified a new member of the tbf1 gene family in the mammalian pathogen Pneumocystis carinii. W ...

Homoeostasis between the GTPase Spg1p and its GAP in the regulation of cytokinesis in S. pombe

Viesturs Simanis, Andrea Krapp, Elena Cano

Cytokinesis in Schizosaccharomyces pombe begins at mitotic entry, when the site of division is defined by formation of the contractile acto-myosin ring (CAR) at the cell cortex. Contraction of the CAR and formation of the division septum are triggered at t ...

The Schizosaccharomyces pombe septation initiation network (SIN) is required for spore formation in meiosis

Viesturs Simanis, Andrea Krapp, Elena Cano

When nutrients are abundant, S. pombe cells grow as rods, dividing by fission after formation of a medially placed cell wall or division septum. Septum formation is triggered by a group of proteins, called the septation initiation network or SIN, that trig ...

Analysis of the S. pombe signalling scaffold protein Cdc11p reveals an essential role for the N-terminal domain in SIN signalling

Viesturs Simanis, Andrea Krapp, Elena Cano

The initiation of cytokinesis in the fission yeast Schizosaccharomyces pombe is signalled by the septation initiation network (SIN). Signalling originates from the spindle pole body (SPB), where SIN proteins are anchored by a scaffold composed of cdc11p an ...

Mitotic hyperphosphorylation of the fission yeast SIN scaffold protein cdc11p is regulated by the protein kinase cdc7p

Viesturs Simanis, Andrea Krapp, Elena Cano

The fission yeast septation initiation network (SIN) triggers the onset of septum formation and cytokinesis. SIN proteins signal from the spindle pole body (SPB), to which they bind in a cell cycle-dependent manner, via the scaffold proteins sid4p and cdc1 ...
