Microtubules are the largest type of filament, with a diameter of about 25 nanometers (nm), and they are composed of a protein called tubulin. Actin filaments are the smallest type, with a ...

Long polymers called microtubules (MT) play a key role in cell division and chemical transport, paving the way for molecular machines and pushing the nucleus apart to split it. Microtubules are ...

Microtubules are major components of the cytoskeleton. They are found in all eukaryotic cells, and they are involved in mitosis, cell motility, intracellular transport, and maintenance of cell shape.

Microtubules are hollow cylindrical structures that play a fundamental role in many biological functions. They are particularly important in cancer-related cellular processes, such as cell ...

Microtubules are composed of a protein called tubulin, which consists of alpha and beta subunits that assemble into large, tube-shaped filaments within the cell. These fibers are dynamic, growing from ...

In 2015, researchers examining deep-sea sediments near the underwater volcano Loki discovered gene fragments indicating a new and previously undiscovered form of microbes. Loki's Castle vent chimney.

Kinetic measurements of kinesin-1's front and rear heads reveal how different neck linker orientation regulate their activity, enabling the motor protein to move in a coordinated manner along ...
