Dynein is a type of motor protein that uses microtubules in the cytoskeleton to carry its cargo. It's kind of a big motor protein. Since it carries its cargo to the minus end of the microtubules, dynein is also known as minus-end-directed motor proteins. That means; Dynein transports cargo from the periphery to the center of the ...
