Kinesin-4 KIF21B limits microtubule growth to allow rapid centrosome polarization in T cells
eLife, 2020 When a T cell and an antigen-presenting cell form an immunological synapse, rapid dynein-driven translocation of the centrosome toward the contact site leads to reorganization of microtubules and associated organelles.

Monitoring Microtubule Mechanical Vibrations via Optomechanical Coupling
, 2016 The possible disruption of a microtubule during mitosis can control the duplication of a cancer cell. Cancer detection and treatment may be possible based on the detection and control of microtubule mechanical oscillations in cells through external ...

Cell proliferation, cell shape, and microtubule and cellulose microfibril organization of tobacco BY-2 cells are not altered by exposure to near weightlessness in space [PDF]
, 2009 The microtubule cytoskeleton and the cell wall both play key roles in plant cell growth and division, determining the plant’s final stature. At near weightlessness, tubulin polymerizes into microtubules in vitro, but these microtubules do not self ...

Structural insight into TPX2-stimulated microtubule assembly
eLife, 2017 During mitosis and meiosis, microtubule (MT) assembly is locally upregulated by the chromatin-dependent Ran-GTP pathway. One of its key targets is the MT-associated spindle assembly factor TPX2.

Nuclear-localized subtype of end-binding 1 protein regulates spindle organization in Arabidopsis [PDF]
, 2010 End-binding 1 (EB1) proteins are evolutionarily conserved plus-end-tracking proteins that localize to growing microtubule plus ends where they regulate microtubule dynamics and interactions with intracellular targets.

Cryo-EM structure of VASH1-SVBP bound to microtubules
eLife, 2020 The dynamic tyrosination-detyrosination cycle of α-tubulin regulates microtubule functions. Perturbation of this cycle impairs mitosis, neural physiology, and cardiomyocyte contraction.

Molecular Mechanisms for Microtubule Length Regulation by Kinesin-8 and XMAP215 Proteins
, 2014 The cytoskeleton is regulated by a plethora of enzymes that influence the stability and dynamics of cytoskeletal filaments. Molecular motors of the kinesin-8 protein family depolymerise microtubules in a length-dependent manner, and experimental and ...

The Role of the Host Cytoskeleton in the Formation and Dynamics of Rotavirus Viroplasms
VirusesRotavirus (RV) replicates within viroplasms, membraneless electron-dense globular cytosolic inclusions with liquid–liquid phase properties. In these structures occur the virus transcription, replication, and packaging of the virus genome in newly ...

eLife, 2020 Intracellular transport relies on multiple kinesins, but it is poorly understood which kinesins are present on particular cargos, what their contributions are and whether they act simultaneously on the same cargo.

Length control of microtubules by depolymerizing motor proteins [PDF]
, 2008 In many intracellular processes, the length distribution of microtubules is controlled by depolymerizing motor proteins. Experiments have shown that, following non-specific binding to the surface of a microtubule, depolymerizers are transported to the ...
