Tracking proteins in the heart of cells

March 5, 2021


In order to stay alive, the cell must provide its various organelles with all the energy elements they need, which are formed in the Golgi apparatus, its centre of maturation and redistribution of lipids and proteins. But how do the proteins that carry these cargoes — the kinesins — find their way and direction within the cell’s “road network” to deliver them at the right place? Chemists and biochemists at the University of Geneva (UNIGE), Switzerland, have discovered a fluorescent chemical dye, making it possible for the first time to track the transport activity of a specific motor protein within a cell. A discovery to be read in the magazine Nature communication.
