Structural models of kinesin I and cytoplasmic dynein

Description

The microtubule-binding portions are on the left and the cargo-binding portions are on the right.

The motor domain of kinesin resembles the S1 headpiece of muscle myosin. The motor domain of dynein binds ATP and contains six different subunits arranged in a circle. The microtubule-binding stalk and the linker to the cargo domain are covalently linked to the hexameric motor domain.
