The family-specific α4-helix of the kinesin-13, MCAK, is critical to microtubule end recognition [PDF]

open access: yesOpen Biology, 2016
Kinesins that influence the dynamics of microtubule growth and shrinkage require the ability to distinguish between the microtubule end and the microtubule lattice.

Abstract P-33: Structural Basis for the Growing Microtubule End Recognition by End Binding Proteins [PDF]

open access: yesInternational Journal of Biomedicine, 2021
Background: Eukaryotic end binding proteins (EBs) can follow the growing microtubule end. EBs play a crucial role in microtubule dynamic instability and promote simultaneously growth rate and catastrophe frequency.

Expression levels of a kinesin-13 microtubule depolymerase modulates the effectiveness of anti-microtubule agents. [PDF]

open access: yesPLoS ONE, 2010
Chemotherapeutic drugs often target the microtubule cytoskeleton as a means to disrupt cancer cell mitosis and proliferation. Anti-microtubule drugs inhibit microtubule dynamics, thereby triggering apoptosis when dividing cells activate the mitotic ...

Dynamics and length distributions of microtubules with a multistep catastrophe mechanism

open access: yesNew Journal of Physics, 2023
Regarding the experimental observation that microtubule (MT) catastrophe can be described as a multistep process, we extend the Dogterom–Leibler model for dynamic instability in order to discuss the effect that such a multistep catastrophe mechanism has ...

TUBA1A tubulinopathy mutants disrupt neuron morphogenesis and override XMAP215/Stu2 regulation of microtubule dynamics

open access: yeseLife, 2022
Heterozygous, missense mutations in α- or β-tubulin genes are associated with a wide range of human brain malformations, known as tubulinopathies. We seek to understand whether a mutation’s impact at the molecular and cellular levels scale with the ...

Chemomechanical Simulation of Microtubule Dynamics With Explicit Lateral Bond Dynamics

open access: yesFrontiers in Physics, 2021
We introduce and parameterize a chemomechanical model of microtubule dynamics on the dimer level, which is based on the allosteric tubulin model and includes attachment, detachment and hydrolysis of tubulin dimers as well as stretching of lateral bonds ...

Lessons from in vitro reconstitution analyses of plant microtubule-associated proteins

open access: yesFrontiers in Plant Science, 2014
Plant microtubules, composed of tubulin GTPase, are irreplaceable cellular components that regulate the directions of cell expansion and cell division, chromosome segregation and cell plate formation.

Janus Compounds, 5-Chloro-N4-methyl-N4-aryl-9H-pyrimido[4,5-b]indole-2,4-diamines, Cause Both Microtubule Depolymerizing and Stabilizing Effects

open access: yesMolecules, 2016
While evaluating a large library of compounds designed to inhibit microtubule polymerization, we identified four compounds that have unique effects on microtubules.

Biochemical reconstitution of branching microtubule nucleation

open access: yeseLife, 2020
Microtubules are nucleated from specific locations at precise times in the cell cycle. However, the factors that constitute these microtubule nucleation pathways and their mode of action still need to be identified. Using purified Xenopus laevis proteins

New insights into the functions and regulations of MAP215/MOR1 and katanin, two conserved microtubule-associated proteins in Arabidopsis

open access: yesPlant Signaling & Behavior, 2023
Plant microtubules (MTs) form highly dynamic and distinct arrays throughout the cell cycle and are essential for cell and organ morphogenesis. A plethora of microtubule associated-proteins (MAPs), both conserved and plant-specific, ensure the dynamic ...
