Dynamic Properties of Molecular Motors in Burnt-Bridge Models
, 2007 Dynamic properties of molecular motors that fuel their motion by actively interacting with underlying molecular tracks are studied theoretically via discrete-state stochastic ``burnt-bridge'' models.

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.

Collective transport of weakly interacting molecular motors with Langmuir kinetics
, 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

Bacteriophages and their structural organisation [PDF]
, 2012 Viruses are extremely small infectious particles that are not visible in a light microscope, and are able to pass through fine porcelain filters. They exist in a huge variety of forms and infect practically all living systems: animals, plants ...

Actomyosin organelle functions of SPIRE actin nucleators precede animal evolution
Communications BiologyAn 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 ...

The Central Role of the F-Actin Surface in Myosin Force Generation
Biology, 2021 Actin is one of the most abundant and versatile proteins in eukaryotic cells. As discussed in many contributions to this Special Issue, its transition from a monomeric G-actin to a filamentous F-actin form plays a critical role in a variety of cellular ...

Kinesin Light Chains Are Essential for Axonal Transport in Drosophila [PDF]
, 1998 Kinesin is a heterotetramer composed of two 115-kD heavy chains and two 58-kD light chains. The microtubule motor activity of kinesin is performed by the heavy chains, but the functions of the light chains are poorly understood.
