Cell cycle regulation, especially faithful DNA replication and mitosis, are crucial to maintain genome stability. Cyclin-dependent kinase (CDK)/cyclin complexes drive most processes in cellular proliferation. In response to DNA damage, cell cycle surveilla ...

Multi-phosphorylation reaction and clustering tune Pom1 gradient mid-cell levels according to cell size

Suliana Manley, Anna Archetti, Lina Carlini, Charlotte Sophia Floderer, Thaïs Reichler

Protein concentration gradients pattern developing organisms and single cells. In Schizosaccharomyces pombe rod-shaped cells, Pom1 kinase forms gradients with maxima at cell poles. Pom1 controls the timing of mitotic entry by inhibiting Cdr2, which forms s ...

Dynamics of protein synthesis and degradation through the cell cycle

David Michael Suter, Andrea Brigitta Alber

Protein expression levels depend on the balance between their synthesis and degradation rates. Even quiescent (G(0)) cells display a continuous turnover of proteins, despite protein levels remaining largely constant over time. In cycling cells, global prot ...

Ramsey-mode Rb cell clock demonstration with a 3D-printed microwave cavity

Anja Skrivervik

We demonstrate operation of a Ramey-mode Rb vapor-cell atomic clock based on a microwave cavity realized by additive manufacturing (3D-printing). The cavity design is based on a loop-gap approach and its critical electrode structure is realized in one mono ...

Active segregation of bacterial chromosomes usually involves the action of ParB proteins, which bind in proximity of chromosomal origin (oriC) regions forming nucleoprotein complexes - segrosomes. Newly duplicated segrosomes are moved either uni- or bidire ...

Genetic depletion of Polo-like kinase 1 leads to embryonic lethality due to mitotic aberrancies

Polo-like kinase 1 (PLK1) is a serine/threonine kinase that plays multiple and essential roles during the cell division cycle. Its inhibition in cultured cells leads to severe mitotic aberrancies and cell death. Whereas previous reports suggested that Plk1 ...

Cortical neurons gradually attain a post-mitotic state

Johannes Gräff

Once generated, neurons are thought to permanently exit the cell cycle and become irreversibly differentiated. However, neither the precise point at which this post-mitotic state is attained nor the extent of its irreversibility is clearly defined. Here we ...

Pombe's thirteen - control of fission yeast cell division by the septation initiation network

Viesturs Simanis

The septation initiation network (SIN) regulates aspects of cell growth and division in Schizosaccharomyces pombe and is essential for cytokinesis. Insufficient signalling results in improper assembly of the contractile ring and failure of cytokinesis, gen ...

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 ...

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

Michaël Unser, Daniel Sage, Jacques Rougemont, Viesturs Simanis, Andrea Krapp, Daniel Andreas Schmitter, 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 ...
