Dynamic Chromatin Invasion and Remodeling by the Transcription Factor Rap1

Maxime Nicolas Mivelaz

Pioneer transcription factors (PTF) are a subset of transcription factors with nucleosome-binding properties allowing them to bind specific sequences in condensed chromatin. Although the biological functions of PTFs including target genes and epigenetic ch ...

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

Pierre Gönczy, 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. ...

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 ...

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 ...

Wnt-controlled sphingolipids modulate Anthrax Toxin Receptor palmitoylation to regulate oriented mitosis in zebrafish

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami

Oriented cell division is a fundamental mechanism to control asymmetric stem cell division, neural tube elongation and body axis extension, among other processes. During zebrafish gastrulation, when the body axis extends, dorsal epiblast cells display divi ...

Site-Specific Hyperphosphorylation Inhibits, Rather than Promotes, Tau Fibrillization, Seeding Capacity, and Its Microtubule Binding

Hilal Lashuel, Mahmood Haj Yahya, Rajasekhar Kolla, Gopinath Pushparathinam

The consistent observation of phosphorylated tau in the pathology of Alzheimer's disease has contributed to the emergence of a model where hyperphosphorylation triggers both tau disassociation from microtubules and its subsequent aggregation. Herein, we ap ...

Spatial control of nucleoporin condensation by fragile X-related proteins

Alessandro Berto

Nucleoporins (Nups) build highly organized nuclear pore complexes (NPCs) at the nuclear envelope (NE). Several Nups assemble into a sieve-like hydrogel within the central channel of the NPCs. In the cytoplasm, the soluble Nups exist, but how their assembly ...

A high-content RNAi screen reveals multiple roles for long noncoding RNAs in cell division

Christina Ernst

Genome stability relies on proper coordination of mitosis and cytokinesis, where dynamic microtubules capture and faithfully segregate chromosomes into daughter cells. With a high-content RNAi imaging screen targeting more than 2,000 human lncRNAs, we iden ...

Traction Forces Control Cell-Edge Dynamics and Mediate Distance Sensitivity during Cell Polarization

Alexander Verkhovskiy, Franck Claude Raynaud, Alicia Carine Bornert, Zeno Messi

Traction forces are generated by cellular actin-myosin system and transmitted to the environment through adhesions. They are believed to drive cell motion, shape changes, and extracellular matrix remodeling [1 -3] . However, most of the traction force anal ...

Ligand Binding to the Collagen VI Receptor Triggers a Talin-to-RhoA Switch that Regulates Receptor Endocytosis

Françoise Gisou van der Goot Grunberg, Matteo Dal Peraro, Laurence Gouzi Abrami, Luciano Andres Abriata, Béatrice Kunz, Shixu Yan

Capillary morphogenesis gene 2 (CMG2/ANTXR2) is a cell surface receptor for both collagen VI and anthrax toxin. Biallelic loss-of-function mutations in CMG2 lead to a severe condition, hyaline fibromatosis syndrome (HFS). We have here dissected a network o ...
