WebFeb 26, 2024 · Dynein, one of three cytoskeletal motor protein families, was first identified a half century ago and got its name after the ‘dyne’ (i.e. a unit of force). Motor proteins are fueled by ATP and ... WebCytoplasmic dynein, which drives various cellular activities such as intracellular transport, is composed of two identical heavy chains (∼550 kDa) belonging to the AAA+ ATPase family and other smaller components. The C-terminal two-thirds of the heavy chain is the motor domain responsible for dynein motility on microtubules.
WebThe core of dynein is composed of a ring of six AAA+ domains, similar to the engines that power the unfolding of proteins in AAA+ proteases. One of these, the AAA1 domain colored dark blue here, is connected to a linker … WebHelder Maiato, in International Review of Cell and Molecular Biology, 2014. 3.5.2 Dynein. Dynein is a large macromolecular complex with a molecular weight of approximately 1.2 MDa. It is composed of heavy intermediate, light intermediate, and light chains.
Cytoplasmic dynein, which has a molecular mass of about 1.5 megadaltons (MDa), is a dimer of dimers, containing approximately twelve polypeptide subunits: two identical "heavy chains", 520 kDa in mass, which contain the ATPase activity and are thus responsible for generating movement along the microtubule; … See more Dyneins are a family of cytoskeletal motor proteins that move along microtubules in cells.
