WebDyneins are found in many eukaryotes, including fungi, worms, insects, and vertebrates, but genome sequence analyses indicate that they are not present in flowering plants. Dynein complexes are composed of one to three heavy chains, and each complex also has various smaller accessory subunits (Tables 1 and 2).Dyneins are classified as either cytoplasmic … WebThe most direct evidence for a role of dynein in retrograde transport of mitochondria is impairment of this process in Drosophila dynein heavy chain mutants. Dynein is part of …

WebAbstract. Mutations in the DYNC1H1 gene encoding for dynein heavy chain cause two closely related human motor neuropathies, dominant spinal muscular atrophy with lower … Each heavy chain has a globular motor domain with a doughnut-shaped structure believed to resemble that of other AAA proteins, a coiled coil "stalk" that binds to the microtubule, and an extended tail (or "stem") that attaches to a neighboring microtubule of the same axoneme. Each dynein molecule thus … See more Dyneins are a family of cytoskeletal motor proteins that move along microtubules in cells. They convert the chemical energy stored in ATP to mechanical work. Dynein transports various cellular cargos, provides forces and … See more Each molecule of the dynein motor is a complex protein assembly composed of many smaller polypeptide subunits.
