An autonomous molecular transport system using DNAs and motor proteins in molecular communication [PDF]

2007 2nd Bio-Inspired Models of Network, Information and Computing Systems, 2007
This paper describes a molecular transport system in molecular communication that uses the machinery in living cells. The molecular transport system requires: 1) loading of the specified cargo molecules at a loading site (at a sender); 2) transport of the loaded cargoes to an unloading site (to a receiver); and 3) unloading of the transported cargoes ...

Golgi fragmentation in ALS motor neurons. New mechanisms targeting microtubules, tethers and transport vesicles.

Frontiers in Neuroscience, 2015
Pathological alterations of the Golgi apparatus, such as its fragmentation represent an early pre-clinical feature of many neurodegenerative diseases and have been widely studied in the motor neuron disease amyotrophic lateral sclerosis (ALS).

Realistic Models of Biological Motion

, 1998
The origin of biological motion can be traced back to the function of molecular motor proteins. Cytoplasmic dynein and kinesin transport organelles within our cells moving along a polymeric filament, the microtubule.

Comparative interactomics analysis of different ALS-associated proteins identifies converging molecular pathways [PDF]

, 2016
Amyotrophic lateral sclerosis (ALS) is a devastating neurological disease with no effective treatment available. An increasing number of genetic causes of ALS are being identified, but how these genetic defects lead to motor neuron degeneration and ...

Localization and function of Kinesin-5-like proteins during assembly and maintenance of mitotic spindles in Silvetia compressa

BMC Research Notes, 2009
Background Kinesin-5 (Eg-5) motor proteins are essential for maintenance of spindle bipolarity in animals. The roles of Kinesin-5 proteins in other systems, such as Arabidopsis, Dictyostelium, and sea urchin are more varied.

Transport by molecular motors in the presence of static defects [PDF]

, 2009
The transport by molecular motors along cytoskeletal filaments is studied theoretically in the presence of static defects. The movements of single motors are described as biased random walks along the filament as well as binding to and unbinding from the

Actomyosin organelle functions of SPIRE actin nucleators precede animal evolution

Communications Biology
An important question in cell biology is how cytoskeletal proteins evolved and drove the development of novel structures and functions. Here we address the origin of SPIRE actin nucleators.

Dynamics of molecular motors in reversible burnt-bridge models

Condensed Matter Physics, 2010
Dynamic properties of molecular motors whose motion is powered by interactions with specific lattice bonds are studied theoretically with the help of discrete-state stochastic "burnt-bridge" models.

Correlation Imaging Reveals Specific Crowding Dynamics of Kinesin Motor Proteins

Physical Review X, 2017
Molecular motor proteins fulfill the critical function of transporting organelles and other building blocks along the biopolymer network of the cell’s cytoskeleton, but crowding effects are believed to crucially affect this motor-driven transport due to ...

Live Imaging of Axonal Transport in the Motor Neurons of Drosophila Larvae

Bio-Protocol, 2017
Axonal transport, which is composed of microtubules, motor proteins and a variety of types of cargo, is a prominent feature of neurons. Monitoring these molecular dynamics is important to understand the biological processes of neurons as well as ...
