A role for the carbon source of the cell and protein kinase A in regulating the S. pombe septation initiation network

Bastien Mangeat, Viesturs Simanis, Andrea Krapp, Özge Uysal Özdemir

The septation initiation network (SIN) is a conserved signal transduction network, which is important for cytokinesis in Schizosaccharomyces pombe. The SIN component Etd1p is required for association of some SIN proteins with the spindle pole body (SPB) du ...

Primary data for "A role for the carbon source of the cell and protein kinase A in regulating the S. pombe septation initiation network"

Bastien Mangeat, Viesturs Simanis, Andrea Krapp, Özge Uysal Özdemir

The Septation Initiation Network (SIN) is a conserved signal transduction network, which is important for cytokinesis in S. pombe. The SIN component Etd1p is required for association of some SIN proteins with the spindle pole body (SPB) during anaphase and ...

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

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

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 ...

Analysis of S. pombe SIN protein association to the SPB reveals two genetically separable states of the SIN

Michaël Unser, Daniel Sage, Viesturs Simanis, Daniel Andreas Schmitter, Andrea Krapp, Jacques Rougemont, Anastasia Chasapi, Ioannis Xenarios

The Schizosaccharomyces pombe septation initiation network (SIN) regulates cytokinesis, and asymmetric association of SIN proteins with the mitotic spindle pole bodies (SPBs) is important for its regulation. Here, we have used semi-automated image analysis ...

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 ...

Dma1-dependent degradation of SIN proteins during meiosis in Schizosaccharomyces pombe

Viesturs Simanis, Andrea Krapp

The Schizosaccharomyces pombe septation initiation network (SIN) is required for cytokinesis during vegetative growth and for spore formation during meiosis. Regulation of the SIN during mitosis has been studied extensively, but less is known about its mei ...

Cytokinesis: Closure resets your SIN

Viesturs Simanis, Andrea Krapp, Evelyn Lattmann

A new study of fission yeast cell division has revealed a coupling between cytoplasmic partitioning and the turning-off of cytokinesis signalling that may be mediated by asymmetric protein distribution. ...

Chemical genetic analysis of the regulatory role of Cdc2p in the S. pombe septation initiation network

Viesturs Simanis, Andrea Krapp

The protein kinase Cdc2p is the master regulator of cell cycle progression in the fission yeast Schizosaccharomyces pombe. It is required both for entry into mitosis and for onset of DNA replication. Cdc2p must be inactivated to permit exit from mitosis, l ...

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 ...

An overview of the fission yeast septation initiation network (SIN)

Viesturs Simanis, Andrea Krapp

The fission yeast septation initiation network, or SIN, is a signal transduction network that is required for septum formation in Schizosaccharomyces pombe. Its activity is tightly regulated through the cell cycle, to ensure proper co-ordination of mitosis ...

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 ...

AtSGP1, AtSGP2 and MAP4K alpha are nucleolar plant proteins that can complement fission yeast mutants lacking a functional SIN pathway

Viesturs Simanis, Andrea Krapp

In the fission yeast Schizosaccharomyces pombe, the onset of septum formation is signalled via the septation initiation network (SIN) involving several protein kinases and a GTPase. Arabidopsis thaliana and Brassica napus proteins homologous to fission yea ...

Recruitment of NIMA kinase shows that maturation of the S. pombe spindle-pole body occurs over consecutive cell cycles and reveals a role for NIMA in modulating SIN activity

Viesturs Simanis, Andrea Krapp

Mitotic exit in Saccharomyces cerevisiae and septation in Schizosaccharomyces pombe are regulated by a conserved signaling network called the mitotic exit and septum initiation networks (SIN), respectively. The network is active on one of the two anaphase ...

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 ...
