Agent-based modeling of intracellular transport [PDF]

open access: yes, 2018
We develop an agent-based model of the motion and pattern formation of vesicles. These intracellular particles can be found in four different modes of (undirected and directed) motion and can fuse with other vesicles. While the size of vesicles follows a

Tango1L but not Tango1S, Tali and cTAGE5 is required for export of type II collagen in medaka fish

open access: yesCell Structure and Function
Newly synthesized proteins destined for the secretory pathway are folded and assembled in the endoplasmic reticulum (ER) and then transported to the Golgi apparatus via COPII vesicles, which are normally 60–90 nm.

Dynein catch bond as a mediator of codependent bidirectional cellular transport

open access: yes, 2019
Intracellular bidirectional transport of cargo on microtubule filaments is achieved by the collective action of oppositely directed dynein and kinesin motors.

Golgi Fragmentation in Neurodegenerative Diseases: Is There a Common Cause?

open access: yesCells, 2019
In most mammalian cells, the Golgi complex forms a continuous ribbon. In neurodegenerative diseases, the Golgi ribbon of a specific group of neurons is typically broken into isolated elements, a very early event which happens before clinical and other ...

Impact of physiological ionic strength and crowding on kinesin-1 motility

open access: yesCell Structure and Function
The motility of biological molecular motors has typically been analyzed by in vitro reconstitution systems using motors isolated and purified from organs or expressed in cultured cells. The behavior of biomolecular motors within cells has frequently been

Spatial control of neuronal metabolism through glucose-mediated mitochondrial transport regulation

open access: yeseLife, 2018
Eukaryotic cells modulate their metabolism by organizing metabolic components in response to varying nutrient availability and energy demands. In rat axons, mitochondria respond to glucose levels by halting active transport in high glucose regions.

Structure, Function and Regulation of the Hsp90 Machinery

open access: yesBiomedical Journal, 2013
Heat shock protein 90 (Hsp90) is an ATP-dependent molecular chaperone which is essential in eukaryotes. It is required for the activation and stabilization of a wide variety of client proteins and many of them are involved in important cellular pathways.

Non-equilibrium forces drive the anomalous diffusion of telomeres in the nucleus of mammalian cells

open access: yesNew Journal of Physics, 2017
Telomeres are vital nucleotide sequences at both ends of each chromosome, and their motion reports on the local dynamics of decondensed chromatin in the nucleus of interphase cells.

Collective transport of weakly interacting molecular motors with Langmuir kinetics

open access: yes, 2015
Filament based intracellular transport involves the collective action of molecular motor proteins. Experimental evidences suggest that microtubule (MT) filament bound motor proteins such as {\it kinesins} weakly interact among themselves during transport

Secondary water pore formation for proton transport in a ClC exchanger revealed by an atomistic molecular dynamics simulation [PDF]

open access: yes, 2008
Several prokaryotic ClC proteins have been demonstrated to function as exchangers that transport both chloride ions and protons simultaneously in opposite directions.
