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. WebDynein has been examined by scanning transmission electron microscopy (STEM). Samples of 30S dynein from tetrahymena cilia were applied to carbon films and either were freeze- dried and examined as unstained, unfixed specimens, or were negatively stained ...
Emerging mechanisms of dynein transport in the cytoplasm …
WebDynein is the large molecular motor that translocates to the (-) ends of microtubules. Dynein was first isolated from Tetrahymena cilia four decades ago. The analysis of the primary structure of the dynein heavy chain and the discovery that many organisms express multiple dynein heavy chains have led to two insights.

WebMar 7, 2000 · The molecular weight of 22S dynein is about two million, and it comprises three different heavy chains and has a three-headed “flower bouquet” structure (11, 12). The kinetics of ATP hydrolysis by 22S dynein is thought to be similar to that of actomyosin . 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. 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. Cytoplasmic and axonemal dynein contain some of the same … See more Segregation of homologous chromosomes to opposite poles of the cell occurs during the first division of meiosis. Proper segregation is essential for producing haploid meiotic … See more • Karp G (2005). Cell and Molecular Biology: Concepts and Experiments (4th ed.).
