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

Conserved mechanisms of microtubule-stimulated ADP release, ATP binding, and force generation in transport kinesins

eLife, 2014
Kinesins are a superfamily of microtubule-based ATP-powered motors, important for multiple, essential cellular functions. How microtubule binding stimulates their ATPase and controls force generation is not understood.

Altered chemomechanical coupling causes impaired motility of the kinesin-4 motors KIF27 and KIF7. [PDF]

, 2018
Kinesin-4 motors play important roles in cell division, microtubule organization, and signaling. Understanding how motors perform their functions requires an understanding of their mechanochemical and motility properties.

Ca2+ Release by IP3 Receptors Is Required to Orient the Mitotic Spindle

Cell Reports, 2020
Summary: The mitotic spindle distributes chromosomes evenly to daughter cells during mitosis. The orientation of the spindle, guided by internal and external cues, determines the axis of cell division and thereby contributes to tissue morphogenesis ...

Regulation of Op18 during Spindle Assembly in Xenopus Egg Extracts [PDF]

, 2001
Oncoprotein 18 (Op18) is a microtubule-destabilizing protein that is negatively regulated by phosphorylation. To evaluate the role of the three Op18 phosphorylation sites in Xenopus (Ser 16, 25, and 39), we added wild-type Op18, a nonphosphorylatable ...

Actin–microtubule coordination at growing microtubule ends [PDF]

Nature Communications, 2014
To power dynamic processes in cells, the actin and microtubule cytoskeletons organize into complex structures. Although it is known that cytoskeletal coordination is vital for cell function, the mechanisms by which cross-linking proteins coordinate actin and microtubule activities remain poorly understood.

Measuring and modeling polymer gradients argues that spindle microtubules regulate their own nucleation

, 2017
Spindles are self-organized microtubule-based structures that segregate chromosomes during cell division. The mass of the spindle is controlled by the balance between microtubule turnover and nucleation. The mechanisms that control the spatial regulation

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.

The Dam1 ring binds to the E-hook of tubulin and diffuses along the microtubule. [PDF]

, 2011
There has been much effort in recent years aimed at understanding the molecular mechanism by which the Dam1 kinetochore complex is able to couple microtubule depolymerization to poleward movement. Both a biased diffusion and a forced walk model have been

Structural state recognition facilitates tip tracking of EB1 at growing microtubule ends

eLife, 2019
The microtubule binding protein EB1 specifically targets the growing ends of microtubules in cells, where EB1 facilitates the interactions of cellular proteins with microtubule plus-ends.
