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 mammalian cells, kinesin plays the same role as do trucks and locomotives within our countries: it is the main driving force behind the transport of manufactured goods. No wheels are involved, ...

Dimers of the molecular motor kinesin can ‘walk’ along microtubules. A flexible neck connects the head of one kinesin of the dimer to its partner. When one head is bound to a microtubule, and when ...

(Nanowerk News) MIT researchers have shown how a cell motor protein exerts the force to move, enabling functions such as cell division. Kinesin, a motor protein that also carries neurotransmitters, ...

Kinesin is a protein motor that ferries membrane-bound packages around cells — but only in one direction. Forcing it into reverse provides clues to its inner workings and to how molecular machines ...

This is a preview. Log in through your library . Abstract Kinesin I can walk on a microtubule for distances as long as several micrometers. However, it is still unclear how this molecular motor can ...

The structure of a key part of the machinery that allows cells to divide has been identified by researchers at the University of California, Davis -- opening new possibilities for throwing a wrench in ...
