The transport protein kinesin is involved in the movement of proteins within a living cell

The video shows how kinesin “walks” along microtubules and pulls a protein-laden vesicle. Kinesin is a kind of “vehicle” that helps proteins move around inside the cell. It works like a train that transports passengers from one station to another. Kinesin attaches to proteins and moves them along special “tracks” inside the cell called microtubules. This allows proteins to reach their intended locations within the cell and perform their functions.
