Neurons are characterized by long processes that allow communication between distant cells. These far-reaching axons and dendrites require extensive intracellular transport, which is largely mediated ...

However, they found the dynein moved far more erratically than kinesin. "In contrast to the precise movement of kinesin, dynein movement involves not only forward steps, but also frequent backward ...

Scientists have made important steps toward understanding how dynein--a "molecular motor"--walks along tube-like structures in the cell to move cellular cargo from the outer structures toward the cell ...

The cell cytoskeleton is modulated by motor proteins, known as dyneins, that generate force and movement on microtubules to control a wealth of biological processes, including motility, cell division, ...

Our cells rely on microscopic highways and specialized protein vehicles to move everything—from positioning organelles to carting protein instructions to disposing of cellular garbage. These highways ...

A mechanism of dynein-powered metastatic locomotion has been identified using soft tissue models, revealing a new clinical target for breast cancer treatment. New research led by Penn State (PA, USA) ...

These proteins are vital to complex life, forming the transport infrastructure that allows different parts of cells to specialise in particular functions. Until now, the way they move has never been ...

The smallest proteins travel in our cells, completing deeply important tasks to keep our molecular mechanisms moving. They are responsible for transporting cargo, duplicating cells and more. Now, a ...

The first images of motor proteins in action are published in the journal Nature Communications today. These proteins are vital to complex life, forming the transport infrastructure that allows ...
