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

Microtubules born on microtubules
![Graphic][1] A new MT is nucleated (white arrowhead) by a γ-TuC (green) that sits on an existing MT bundle.Microtubule (MT) arrays form, say Janson et al. ( [page 297][2]), when MT nucleators stick to existing MTs.

Structural plasticity of the living kinetochore [PDF]
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 ...

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 ...

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

Are microtubules tension sensors? [PDF]
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.

Modeling the Effects of Drug Binding on the Dynamic Instability of Microtubules
We propose a stochastic model that accounts for the growth, catastrophe and rescue processes of steady state microtubules assembled from MAP-free tubulin.

Monitoring Microtubule Mechanical Vibrations via Optomechanical Coupling
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 ...

Directional instability of microtubule transport in the presence of kinesin and dynein, two opposite polarity motor proteins. [PDF]
Kinesin and dynein are motor proteins that move in opposite directions along microtubules. In this study, we examine the consequences of having kinesin and dynein (ciliary outer arm or cytoplasmic) bound to glass surfaces interacting with the same ...

Autophagy in cancer and protein conformational disorders
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.
