Cellular processes are regulated through the balance between protein shapes that confer active or inactive functions. In the complexity of cellular regulations, the preferred shape (or conformation) of a protein often depends on the binding of another molecule (called effector), thus implying that the same protein can exert distinct functions depending on the effector it binds to. At the molecular level, protein functions thus translate into protein dynamics, which is key for the development of all cellular processes, from cell division to energy provision and cell fate determination.
