Centriole Biogenesis: From Identifying the Characters to Understanding the Plot

Pierre Gönczy, Niccolo Banterle

The centriole is a beautiful microtubule-based organelle that is critical for the proper execution of many fundamental cellular processes, including polarity, motility, and division. Centriole biogenesis, the making of this miniature architectural wonder, ...

Dynein Transmits Polarized Actomyosin Cortical Flows to Promote Centrosome Separation

Pierre Gönczy, Alessandro De Simone

The two centrosomes present at the onset of mitosis must separate in a timely and accurate fashion to ensure proper bipolar spindle assembly. The minus-end-directed motor dynein plays a pivotal role in centrosome separation, but the underlying mechanisms r ...

Kinetic and structural roles for the surface in guiding SAS-6 self-assembly to direct centriole architecture

Pierre Gönczy, Georg Fantner, Adrian Pascal Nievergelt, Santiago Harald Andany, Niccolo Banterle, Georgios Hatzopoulos, Charlène Cécile Geneviève Brillard

Discovering mechanisms governing organelle assembly is a fundamental pursuit in biology. The centriole is an evolutionarily conserved organelle with a signature 9-fold symmetrical chiral arrangement of microtubules imparted onto the cilium it templates. Th ...

Discovery of a Selective Aurora A Kinase Inhibitor by Virtual Screening

Pierre Gönczy, Sachin Kotak, Maria Josefina Marcaida Lopez

Here we report the discovery of a selective inhibitor of Aurora A, a key regulator of cell division and potential anticancer target. We used the atom category extended ligand overlap score (xLOS), a 3D ligand-based virtual screening method recently develop ...

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 ...

Physically asymmetric division of the C. elegans zygote ensures invariably successful embryogenesis

Pierre Gönczy, Radek Jankele

Asymmetric divisions that yield daughter cells of different sizes are frequent during early embryogenesis, but the importance of such a physical difference for successful development remains poorly understood. Here, we investigated this question using the ...

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

Pierre Gönczy

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 ...

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

Kai Johnsson, Pierre Gönczy, Luc Reymond, Grazvydas Lukinavicius

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 ...

Mechanisms of procentriole formation

Pierre Gönczy, Petr Strnad

The centrosome comprises a pair of centrioles and associated pericentriolar material, and it is the principal microtubule-organizing centre of most animal cells. Like the genetic material, the centrosome is duplicated once and only once during the cell cyc ...

Centriole elimination during Caenorhabditis elegans oogenesis initiates with loss of the central tube protein SAS-1

Pierre Gönczy, Coralie Busso, Mary-Claude Croisier-Coeytaux, Alexander Woglar, Marie Juliette Ségolène Pierron, Tamara Mikeladze-Dvali, Keshav Jha

In most metazoans, centrioles are lost during oogenesis, ensuring that the zygote is endowed with the correct number of two centrioles, which are paternally contributed. How centriole architecture is dismantled during oogenesis is not understood. Here, we ...

NuMA interacts with phosphoinositides and links the mitotic spindle with the plasma membrane

Pierre Gönczy, Coralie Busso, Sachin Kotak

The positioning and the elongation of the mitotic spindle must be carefully regulated. In human cells, the evolutionary conserved proteins LGN/Gai1-3 anchor the coiled-coil protein NuMA and dynein to the cell cortex during metaphase, thus ensuring proper s ...

Towards a molecular architecture of centriole assembly

Pierre Gönczy

The centriole is an evolutionarily conserved macromolecular structure that is crucial for the formation of flagella, cilia and centrosomes. The ultrastructure of the centriole was first characterized decades ago with the advent of electron microscopy, reve ...

Cell-free reconstitution reveals centriole cartwheel assembly mechanisms

Pierre Gönczy, Henning Paul-Julius Stahlberg, Paul Guichard, Mircea Ioan Iacovache, Virginie Hamel, Niccolo Banterle, Veronika Nemcíková Villímová

How cellular organelles assemble is a fundamental question in biology. The centriole organelle organizes around a nine-foldsymmetrical cartwheel structure typically 100 nm high comprising a stack of rings that each accommodates nine homodimers of SAS-6 pro ...

Phosphorylation of SAS-6 by ZYG-1 is critical for centriole formation in C. elegans embryos

Pierre Gönczy, Coralie Busso

Despite being essential for proper cell division, the mechanisms governing centrosome duplication are incompletely understood and represent an important open question in cell biology. Formation of a new centriole next to each existing one is critical for c ...

Chemical Probe for Imaging of Polo-like Kinase 4 and Centrioles

Kai Johnsson, Pierre Gönczy, Luc Reymond, Georgios Hatzopoulos, Aleksandar Salim

Polo-like kinase (Plk4) is a serine/threonine-proteinkinase thatis essential for biogenesis of the centriole organelle and is enrichedat centrioles. Herein, we introduce Cen-TCO, a chemical probe basedon the Plk4 inhibitor centrinone, to image Plk4 and cen ...

Centrosome duplication and nematodes: recent insights from an old relationship

Pierre Gönczy

Centrosome duplication is required for proper cell division, and centriole formation is a key step in this process. This review discusses recent studies in C. elegans that have identified five core proteins required for centriole formation, thus shedding l ...
