Structures of SAS-6 coiled coil hold implications for the polarity of the centriolar cartwheel

Centrioles are eukaryotic organelles that template the formation of cilia and flagella, as well as organize the microtubule network and the mitotic spindle in animal cells. Centrioles have proximal-distal polarity and a 9 fold radial symmetry imparted by a ...

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 ...

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 ...

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. ...

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 ...

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 ...

Structure and transformation of bacteriophage A511 baseplate and tail upon infection of Listeria cells

Sergey Nazarov, Petr Leiman, Ricardo Cesar Guerrero Ferreira

Contractile injection systems (bacteriophage tails, type VI secretions system, R-type pyocins, etc.) utilize a rigid tube/contractile sheath assembly for breaching the envelope of bacterial and eukaryotic cells. Among contractile injection systems, bacteri ...

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 ...
