Grand canonical Brownian dynamics simulations of adsorption and self-assembly of SAS-6 rings on a surface

The Spindle Assembly Abnormal Protein 6 (SAS-6) forms dimers, which then self-assemble into rings that are critical for the nine-fold symmetry of the centriole organelle. It has recently been shown experimentally that the self-assembly of SAS-6 rings is st ...

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

Pierre Gönczy, Santiago Harald Andany, Georg Fantner, Adrian Pascal Nievergelt, Georgios Hatzopoulos, Niccolo Banterle, 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 ...

Tuning SAS-6 architecture with monobodies impairs distinct steps of centriole assembly

Tatiana Favez, Pierre Gönczy, Virginie Hamel, Santiago Harald Andany, Georg Fantner, Oliver Hantschel, Georgios Hatzopoulos, Niccolo Banterle

Centrioles are evolutionarily conserved multi-protein organelles essential for forming cilia and centrosomes. Centriole biogenesis begins with self-assembly of SAS-6 proteins into 9-fold symmetrical ring polymers, which then stack into a cartwheel that sca ...

Homogeneous multifocal excitation for high-throughput super-resolution imaging

Pierre Gönczy, Virginie Hamel, Suliana Manley, Paul Guichard, Dora Mahecic, Kyle Michael Douglass, Denis Fortun, Niccolo Banterle, Khalid Ashraf Mohie Ibrahim, Davide Gambarotto

Super-resolution microscopies have become an established tool in biological research. However, imaging throughput remains a main bottleneck in acquiring large datasets required for quantitative biology. Here we describe multifocal flat illumination for fie ...

High-speed photothermal off-resonance atomic force microscopy reveals assembly routes of centriolar scaffold protein SAS-6

Pierre Gönczy, Santiago Harald Andany, Georg Fantner, Adrian Pascal Nievergelt, Niccolo Banterle

The self-assembly of protein complexes is at the core of many fundamental biological processes1, ranging from the polymerization of cytoskeletal elements, such as microtubules2, to viral capsid formation and organelle assembly3. To reach a comprehensive un ...

Multicolor single-particle reconstruction of protein complexes

Pierre Gönczy, Suliana Manley, Kyle Michael Douglass, Christian Sieben, Niccolo Banterle

Single-particle reconstruction (SPR) from electron microscopy (EM) images is widely used in structural biology, but it lacks direct information on protein identity. To address this limitation, we developed a computational and analytical framework that reco ...

Cell-free reconstitution reveals centriole cartwheel assembly mechanisms

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

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 ...

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, ...
