Transport by molecular motor proteins (Kinesin, Dynein and unconventional Myosin) is essential for cell functioning and survival.
Several models have been proposed in recent year to understand the transport by multiple motors.
The mean-field model is useful for describing transport by a large group of motors.
In mean-field description, fluctuation in the forces that individual motors feel while pulling the cargo is ignored.
In stochastic model, fluctuation in the forces that motors feel are not ignored.
