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?

Unlike a congested city commute, cellular traffic is efficient and highly regulated - thanks in part to a group of proteins known as motor molecules that use microtubules to haul vital cargo through ...

Kinesin is a motor protein that drives intracellular transport by stepping along microtubules in a hand-over-hand manner. Advanced dark-field microscopy has made it possible to capture the gait of ...

Kinesin is a homodimeric motor with two catalytic heads joined to a stalk via short neck linkers (NLs). We measured the torsional properties of single recombinant molecules by tracking the thermal ...

The inside of a living cell has been compared to a train station at rush hour, with enzymes, chromosomes and other internal components constantly being shuttled along tiny fibrous tracks called ...
