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

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

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 ...

Novel features of centriole polarity and cartwheel stacking revealed by cryo-tomography

Davide Demurtas, Georgios Hatzopoulos, Sergey Nazarov, Alexandra Bezler, Paul Guichard, Veronika Nemcíková Villímová

Centrioles are polarized microtubule-based organelles that seed the formation of cilia, and which assemble from a cartwheel containing stacked ring oligomers ofSAS-6 proteins. A cryo-tomography map of centrioles from the termite flagellateTrichonymphaspp. ...

Role of the RNA-binding protein Bicaudal-C1 and interacting factors in cystic kidney diseases

Daniel Constam, Benjamin Marcel Daniel Rothé, Céline Gagnieux, Lucía Carolina Leal Esteban

Polycystic kidneys frequently associate with mutations in individual components of cilia, basal bodies or centriolar satellites that perturb complex protein networks. In this review, we focus on the RNA-binding protein Bicaudal-C1 (BICC1) which was found m ...

A helical inner scaffold provides a structural basis for centriole cohesion

Henning Paul-Julius Stahlberg, Davide Gambarotto, Paul Guichard, Virginie Hamel

The ninefold radial arrangement of microtubule triplets (MTTs) is the hallmark of the centriole, a conserved organelle crucial for the formation of centrosomes and cilia. Although strong cohesion between MTTs is critical to resist forces applied by ciliary ...

Architecture of the centriole cartwheel‐containing region revealed by cryo‐electron tomography

Henning Paul-Julius Stahlberg, Paul Guichard, Virginie Hamel

Centrioles are evolutionarily conserved barrels of microtubule triplets that form the core of the centrosome and the base of the cilium. While the crucial role of the proximal region in centriole biogenesis has been well documented, its native architecture ...

Centriole foci persist in starfish oocytes despite Polo-like kinase 1 inactivation or loss of microtubule nucleation activity

Pierre Gönczy, Nils Kalbfuss, Marie Juliette Ségolène Pierron

Centrioles must be eliminated or inactivated from the oocyte to ensure that only the two functional centrioles contributed by the sperm are present in the zygote. Such removal can occur during oogenesis, as in Drosophila, where departure of Polo kinase fro ...

Centriole assembly at a glance

Pierre Gönczy, Georgios Hatzopoulos

The centriole organelle consists of microtubules (MTs) that exhibit a striking 9-fold radial symmetry. Centrioles play fundamental roles across eukaryotes, notably in cell signaling, motility and division. In this Cell Science at a Glance article and accom ...

Integrative approach to analyze the proximal region of the Trichonympha agilis centriole

Veronika Nemcíková Villímová

The centrosome, the major microtubule organizing center in animal cells, is composed of two orthogonally arranged centrioles and surrounding pericentriolar material. Centrioles are evolutionary conserved organelles characterized by a nine-fold symmetry of ...

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 ...
