Dynein-dynactin
WebCytoplasmic dynein and dynactin are megadalton-sized multisubunit molecules that function together as a cytoskeletal motor. In the present study, we explore the mechanism of dynein-dynactin binding in vitro and then extend our findings to an in vivo context. Solution binding assays were used to define binding domains in the dynein intermediate chain … WebMar 11, 2016 · Introduction. Cytoplasmic dynein is the predominant minus-end-directed microtubule motor in living cells (Allan, 2011; Vallee et al, 2012; Roberts et al, 2013).In metazoans, dynein is not strongly processive on its own, and long-range directional movement requires dynein's association with the large dynactin complex, which is …

From a genetic screen for mutations affecting early-endosome distribution in Aspergillus nidulans, we identified … 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.
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 ... WebNormal Function. The DYNC1H1 gene provides instructions for making a protein that is part of a group (complex) of proteins called dynein. This complex is found in the fluid inside cells (cytoplasm). Dynein is turned on (activated) by attaching (binding) to another complex called dynactin. This dynein-dynactin complex binds to various materials ...
