WebJun 12, 2007 · Cytoplasmic dynein is a minus end-directed microtubule motor protein responsible for the transport of vesicles and organelles toward the cell center. Dynactin is a dynein activator that binds to both dynein and the microtubule. The dynein/dynactin complex is essential for a diversity of cellular trafficking events, such as vesicular … WebFeb 24, 2009 · Brain NF-κB has been reported to coimmunoprecipitate dynein intermediate chain and components of dynactin in the presence of cross-linkers , and dynein is also concentrated at the postsynaptic density in neurons and recruited to the immunological synapse in T cells , both sites which can signal NF-κB activation. We have now shown …
WebThe dynein/dynactin motor complex localizes transiently to kinetochores and is implicated in chromosome segregation, but its role remains poorly understood. Here, we use the Caenorhabditis elegans embryo to investigate the function of kinetochore dynein by analyzing the Rod/Zwilch/Zw10 (RZZ) complex and the associated coiled-coil protein … WebFeb 5, 2007 · Cytoplasmic dynein is an ∼1.2-MD multisubunit protein complex, and it is the major motor for centripetal transport of membranous cargoes along microtubules (Schroer et al., 1989).Dynactin, which is also an ∼1.2-MD multisubunit complex, is a critical component of most, if not all, of the cytoplasmic dynein–driven activities.
Dynein and dynactin were reported to interact directly by the binding of dynein intermediate chains with p150 . The affinity of this interaction is around 3.5μM. Dynein and dynactin do not run together in a sucrose gradient, but can be induced to form a tight complex in the presence of the N-terminal 400 amino acids of Bicaudal D2 (BICD2), a cargo adaptor that links dynein and dynactin to Golgi derived vesicles. In the presence of BICD2, dynactin binds to dynein and activ… WebSep 7, 2024 · Cytoplasmic dynein is a microtubule motor that is activated by its cofactor dynactin and a coiled-coil cargo adaptor1–3. Up to two dynein dimers can be recruited per dynactin, and interactions ...
