Multiple motors cooperate to establish and maintain acentrosomal spindle bipolarity in C. elegans oocyte meiosis

open access: yeseLife, 2022
While centrosomes organize spindle poles during mitosis, oocyte meiosis can occur in their absence. Spindles in human oocytes frequently fail to maintain bipolarity and consequently undergo chromosome segregation errors, making it important to understand

Isolation of Microtubules and Microtubule Proteins

open access: yesCurrent Protocols in Cell Biology, 2008
AbstractThis unit describes various protocols for the isolation and purification of the main constituents of microtubules, chiefly α‐ and β‐tubulin, and the most significant microtubule associated proteins (MAPs), specifically MAP1A, MAP1B, MAP2, and tau.

Intrinsic and Extrinsic Factors Affecting Microtubule Dynamics in Normal and Cancer Cells

open access: yesMolecules, 2020
Microtubules (MTs), highly dynamic structures composed of α- and β-tubulin heterodimers, are involved in cell movement and intracellular traffic and are essential for cell division.

Tubulin bond energies and microtubule biomechanics determined from nanoindentation in silico [PDF]

open access: yes, 2015
Microtubules, the primary components of the chromosome segregation machinery, are stabilized by longitudinal and lateral non-covalent bonds between the tubulin subunits.

CENP-F stabilizes kinetochore-microtubule attachments and limits dynein stripping of corona cargoes [PDF]

open access: yes, 2020
Accurate chromosome segregation demands efficient capture of microtubules by kinetochores and their conversion to stable bioriented attachments that can congress and then segregate chromosomes.

The Tubulin Code in Mitosis and Cancer

open access: yesCells, 2020
The “tubulin code” combines different α/β-tubulin isotypes with several post-translational modifications (PTMs) to generate microtubule diversity in cells.

Dynamic Dissection of Dynein and Kinesin-1 Cooperatively Mediated Intercellular Transport of Porcine Epidemic Diarrhea Coronavirus along Microtubule Using Single Virus Tracking

open access: yesVirulence, 2021
It is now clear that the intercellular transport on microtubules by dynein and kinesin-1 motors has an important role in the replication and spread of many viruses.

Structural plasticity of the living kinetochore [PDF]

open access: yes, 2017
The kinetochore is a large, evolutionarily conserved protein structure that connects chromosomes with microtubules. During chromosome segregation, outer kinetochore components track depolymerizing ends of microtubules to facilitate the separation of ...

Mammalian kinetochores count attached microtubules in a sensitive and switch-like manner. [PDF]

open access: yes, 2019
The spindle assembly checkpoint (SAC) prevents anaphase until all kinetochores attach to the spindle. Each mammalian kinetochore binds many microtubules, but how many attached microtubules are required to turn off the checkpoint, and how the kinetochore ...
