Tracking proteins in the heart of cells (IMAGE) Université de Genève Caption A precipitating dye generates fluorescent, aster-like crystals (green) in live cells recording the motion of the motor protein kinesin-1 along microtubules. The crystals are centred in the Golgi apparatus (magenta) and extends towards the periphery of the cells, consistently with the transport activity of kinesin-1.
