Tubulin dimers polymerize to form microtubules, which generally consist of 13 linear protofilaments assembled around a hollow core. The protofilaments are composed of head-to-tail arrays of tubulin dimers and are arranged in parallel. Consequently, microtubules (like actin filaments) are polar structures with two distinct ends: a fast-growing plus end and a slow-growing minus end. As the polarity of actin filaments defines the direction of myosin movement, this polarity is considered to be very important in determining the direction of movement along microtubules,
