Abstract OR-8: High-Resolution Structures of Microtubule-Drug Complexes Revealed by Cryo-EM [PDF]

International Journal of Biomedicine, 2019
Background: Microtubules are dynamic protein filaments that are crucial for cell division and constitute key elements of the cytoskeleton. They are assembled from αβ-tubulin heterodimers that form hollow cylindrical structures. There is a large number of

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 ...

NAP (davunetide) rescues neuronal dysfunction in a Drosophila model of tauopathy [PDF]

, 2013
Alzheimer’s disease (AD) is a devastating neurodegenerative disease causing irreversible cognitive decline in the elderly. There is no disease-modifying therapy for this condition and the mechanisms underpinning neuronal dysfunction and neurodegeneration

Microtubule-severing enzymes: From cellular functions to molecular mechanism. [PDF]

, 2018
Microtubule-severing enzymes generate internal breaks in microtubules. They are conserved in eukaryotes from ciliates to mammals, and their function is important in diverse cellular processes ranging from cilia biogenesis to cell division, phototropism ...

Microtubules in Plants [PDF]

The Arabidopsis Book, 2015
Microtubules (MTs) are highly conserved polar polymers that are key elements of the eukaryotic cytoskeleton and are essential for various cell functions. αβ-tubulin, a heterodimer containing one structural GTP and one hydrolysable and exchangeable GTP, is the building block of MTs and is formed by the sequential action of several molecular chaperones ...

Modeling the Effects of Drug Binding on the Dynamic Instability of Microtubules

, 2011
We propose a stochastic model that accounts for the growth, catastrophe and rescue processes of steady state microtubules assembled from MAP-free tubulin.

Autophagy in cancer and protein conformational disorders

FEBS Letters, EarlyView.
Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

The human SKA complex drives the metaphase-anaphase cell cycle transition by recruiting protein phosphatase 1 to kinetochores

eLife, 2016
The spindle- and kinetochore-associated (Ska) complex is essential for normal anaphase onset in mitosis. The C-terminal domain (CTD) of Ska1 binds microtubules and was proposed to facilitate kinetochore movement on depolymerizing spindle microtubules ...

Are microtubules tension sensors? [PDF]

Nature Communications, 2019
AbstractMechanical signals play many roles in cell and developmental biology. Several mechanotransduction pathways have been uncovered, but the mechanisms identified so far only address the perception of stress intensity. Mechanical stresses are tensorial in nature, and thus provide dual mechanical information: stress magnitude and direction.
