Ron Vale Recounts How a Control Experiment Revealed Kinesin, the Microtubule Motor Protein
Start here
Ron Vale has recounted the discovery of kinesin, a motor protein that moves organelles along microtubules. Working at Woods Hole's Marine Biological Laboratory, he applied video-enhanced microscopy developed by Allen, Inoué and colleagues to visualize axonal transport in squid axons directly for the first time. A control experiment, designed to rule out interference from soluble protein fragments, instead confirmed that organelles themselves move along microtubules. That result led to the purification of kinesin and reshaped Vale's own research trajectory. His account places the discovery within the technical advances in light microscopy that made direct observation of intracellular transport possible.

Ron Vale tells the story of how kinesin, a motor protein that moves organelles along microtubules, was discovered. Work at Woods Hole (MBL) used video-enhanced microscopy developed by Allen, Inoué and others to visualize axonal transport in squid axons directly for the first time. A control experiment meant to rule out interference from soluble protein fragments instead confirmed that organelles themselves move along microtubules, leading to the purification of kinesin and a change in Vale's own research trajectory.
