The movement  microtubules mostly occurs in the direction of the plus end, meaning cellular cargo is transported from the center of the cell to the periphery.

How do micro tubules move?

The movements of cilia and flagella result from the sliding of outer micro tubule doublets relative to one another, powered by the motor activity of axonemal dynein. The dynein bases bind to the A tubules while the dynein head groups bind to the B tubules of adjacent doublets

How do motor proteins move in one direction?

Motor proteins use energy derived from the hydrolysis of ATP to move uni directionally along micro tubules and actin filaments.

What do micro tubule associated proteins do?

Micro tubule-associated proteins (MAPs) regulate assembly and stability of micro tubules. Micro tubules constitute a major part of the cyto-skeleton and are important in cyto skeletal rearrangements during neuronal growth, axon guidance, and synapse formation.
