Life's smallest motor, a protein that shuttles cargo within cells and helps cells divide, does so by rocking up and down like a seesaw, according to research conducted by scientists at the U.S.

For decades, scientists have known that motor proteins like kinesin-2 ferry vital cargo along microtubule "highways" inside cells. But how these molecular vehicles identify and bind to the right cargo ...

Biophysicists at Stanford University have finally answered one of the most fundamental questions in molecular biology: How does the tiny motor molecule, known as kinesin, move across a living cell?

Inside neurons, motor proteins haul precious cargo, moving essential goods along thread-like roadways called microtubule tracks. This miniature highway system is vital for keeping neurons healthy: ...

Kinesin proteins eat away at microtubules, shortening them and pulling chromosomes to opposite spindle poles during cell division in most organisms. However, fission yeast lacks these proteins, and ...

Researchers detail the mechanism that allows propofol, a common anesthetic, to halt the movement of kinesin proteins that deliver cargoes to the far reaches of cells. Like a wrench that gums up the ...

Regulation of organelle transport by molecular motors along the cytoskeletal microtubules is central to maintaining cellular functions. Here, we show that the ubiquitous tau-related ...

As organisms grow, live, and move through the world, they're subjected to an array of internal and external forces. Biological forms must be able to withstand the stresses of stretching and ...
