dynein

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.

dynein

/dy·ne·in/ (di´nēn) an ATP-splitting enzyme essential to the motility of cilia and flagella because of its interactions with microtubules.

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.

Usually, the axoneme is formed by nine outer doublet microtubules and two central singlet microtubules (the 9+2 pattern); the active sliding of microtubules by axonemal dyneins and proper assembly of all cytoskeletal elements is critical for sperm motility (Inaba, 2003).
RHAMM is a centrosomal protein that interacts with dynein and maintains spindle pole stability.
Tektins are microtubule-associated cytoskeletal proteins essential for generating complex, long-range patterns of binding sites for axonemal components, such as nexins, radial spokes, and dynein arms (Norrander et al.
These defects include lack of inner and/or outer dynein arms, defective radial spokes, ciliary disorientation, and ciliary transposition.
Indeed, the cytoplasmic motor protein dynein, a protein involved in the movement of chromosomes and positioning the mitotic spindles for cell division, is an early target for destruction during apoptosis (Karp, 2005).

The deletion of dynein light chain binding site in P protein which is necessary for axonal transport of the virus reduces peripheral infectivity of the recombinant virus in suckling mice (89).
Specific topics include molecular dynamics simulation studies of couples protein and water dynamics, heat transfer in nanostructures, energy flow pathways in photoreceptor proteins, and the chemo-mechanical coupling mechanisms of kinesin and dynein.
Afzelius and colleagues showed that in people with Kartagener syndrome, certain cilia are missing protein structures called the dynein arms, which make up the motor that allows the cilia to move.
As mitochondria are the major source of the ATP that helps in the movement of the sperm, the mitochondria produce ATP that diffuses downwards to the axonemal microtubules and their dynein arms.
