dynein

 [di´ne-in]
a protein from the microtubules of cilia and flagella, which functions as an ATP-splitting enzyme and is essential to the motility of cilia and flagella.

dyn·ein

(dīn'ēn),
A protein associated with motile structures that exhibits adenosine triphosphatase activity; it forms "arms" on the outer microtubules of cilia and flagella. It functions as a molecular motor.
See also: tubulin, dynein arm.
[dyne + protein]

dynein

(dī′nēn′, -nē-ĭn)
n.
Any of a group of motor proteins that move along microtubules and are involved in intracellular transport of organelles and movement of cilia and flagella.

dyn·ein

(dīn'ēn)
A protein associated with motile structures, exhibiting adenosine triphosphatase activity; it forms "arms" on the outer tubules of cilia and flagella.
See also: tubulin

The motive force of flagellar motility is exerted by axonemal dyneins, which are phylogenetically distinct from cytoplasmic dyneins. Studies on the molecular structure of outer arm dynein have been more advanced than those on the inner arm dynein because the former can be easily purified from the axonemes (31) and is present as a single molecular species in flagella and cilia.
Loss of all or some of the dynein family members, including outer arm, inner arm and cytoplasmic dyneins, is a feature of the dynein history in eukaryotes.
