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

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 ...

Selective Chemical Crosslinking Reveals a Cep57-Cep63-Cep152 Centrosomal Complex

Kai Johnsson, Pierre Gönczy, Luc Reymond, Grazvydas Lukinavicius, Keitaro Umezawa

The centrosome functions as the main microtubule-organizing center of animal cells and is crucial for several fundamental cellular processes [1]. Abnormalities in centrosome number and composition correlate with tumor progression [2, 3] and other diseases ...

Centrosomal MPF triggers the mitotic and morphogenetic switches of fission yeast

Viesturs Simanis, Andrea Krapp

Activation of mitosis-promoting factor (MPF) drives mitotic commitment. In human cells active MPF appears first on centrosomes. We show that local activation of MPF on the equivalent organelle of fission yeast, the spindle pole body (SPB), promotes Polo ki ...

MISP is a novel Plk1 substrate required for proper spindle orientation and mitotic progression

Pierre Gönczy, Sachin Kotak

Precise positioning of the mitotic spindle determines the correct cell division axis and is crucial for organism development. Spindle positioning is mediated through a cortical machinery by capturing astral microtubules, thereby generating pushing/pulling ...

The SCF-FBXW5 E3-ubiquitin ligase is regulated by PLK4 and targets HsSAS-6 to control centrosome duplication

Pierre Gönczy, Debora Keller

Deregulated centrosome duplication can result in genetic instability and contribute to tumorigenesis(1,2). Here, we show that centrosome duplication is regulated by the activity of an E3-ubiquitin ligase that employs the F-box protein FBXW5 (ref. 3) as its ...

PP2A Phosphatase Acts upon SAS-5 to Ensure Centriole Formation in C. elegans Embryos

Pierre Gönczy, Debora Keller

Centrosome duplication occurs once per cell cycle and ensures that the two resulting centrosomes assemble a bipolar mitotic spindle. Centriole formation is fundamental for centrosome duplication. In Caenorhabditis elegans, the evolutionarily conserved prot ...

Phosphorylation of synucleins by members of the Polo-like kinase family

Hilal Lashuel, Harald Hirling, Magdalena Zweckstetter, Abid Oueslati, Martial Mbefo Kamdem

Phosphorylation of alpha-synuclein (alpha-syn) at Ser-129 is a hallmark of Parkinson disease and related synucleinopathies. However, the identity of the natural kinases and phosphatases responsible for regulating alpha-syn phosphorylation remain unknown. H ...

Uncovering the Physics of Frustrated Quantum Magnets using the Correlation Density Matrix Approach

This work is devoted to the study, the development, and the application of a new systematic method yielding the dominant correlations that govern a quantum many-body state in an unbiased way. The dominant correlations between any two disjoint blocks of a s ...

Overly long centrioles and defective cell division upon excess of the SAS-4-related protein CPAP

Pierre Gönczy, Gregor Kohlmaier

The centrosome is the principal microtubule organizing center (MTOC) of animal cells. Accurate centrosome duplication is fundamental for genome integrity and entails the formation of one procentriole next to each existing centriole, once per cell cycle. Th ...

PLK-1 asymmetry contributes to asynchronous cell division of C. elegans embryos

Pierre Gönczy, Yemima Suryani Budirahardja

Acquisition of lineage-specific cell cycle duration is an important feature of metazoan development. In Caenorhabditis elegans, differences in cell cycle duration are already apparent in two-cell stage embryos, when the larger anterior blastomere AB divide ...
