Cytoskeletal Motor Proteins
Motor proteins utilizing the cytoskeleton for movement fall into two categories based on their substrates: Actin motors such as myosin move along microfilaments through interaction with actin. Microtubule motors such as dynein and kinesin move along microtubules through interaction with tubulin. There are two basic types of microtubule motors: plus-end motors and minus-end motors, depending on the direction in which they "walk" along the microtubule cables within the cell.

Famous quotes containing the words motor and/or proteins:
“We disparage reason.
But all the time it’s what we’re most concerned with.
There’s will as motor and there’s will as brakes.
Reason is, I suppose, the steering gear.”
—Robert Frost (1874–1963)
“Civilization means food and literature all round. Beefsteaks and fiction magazines for all. First-class proteins for the body, fourth-class love-stories for the spirit.”
—Aldous Huxley (1894–1963)
