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.

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.

In August, Avon scientists announced what they called an "anti-aging breakthrough," saying they had solved "a key piece of the skin-aging puzzle." The team of researchers focused on a transporter protein called dynein, which plays a critical role in carrying nutrients as well as mitochondria, the "powerhouses" within cells, to where they are needed, keeping skin cells productive and functioning optimally.

It is associated with mutations in genes, mainly affecting DNAI1 on 17 chromosome 9p21-p13, DNAI2, DNAH5 14 chromosome 5p15p14, DNAH11 on 18 chromosome 7p21, thioredoxin domain containing 3 (TXNDC3), radial spoke head 9 homologue (RSPH9) and 4 homologue A (RSPH4A), which results in numerous defects including structural abnormalities of the dynein arms, radial spokes, and microtubules of the cilia.2,6,7
