Welcome to Molecular Steppers, a creation borne out of passion for the nano world of bi-pedaling motor proteins and their mechanisms of action.

Molecular Steppers strives to educate and engage aspiring scientists and those keen to understand what gives these tiny machines the power to haul cellular cargos up and down the length of a nerve fiber or across the crowded environment of a cell.

Dynein walks at a rate of ~100 steps per second or 40 times faster than in this animation.
