Dynein heavy chain-like protein
WebFeb 12, 2015 · Dynactin works with the cytoplasmic dynein-1 motor (dynein) to transport cargos along the microtubule cytoskeleton (1–3).Together, these protein complexes maintain the cell’s spatial organization, return components from the cell’s periphery, and assist with cellular division ().Mutations in either complex cause neurodegeneration (), … WebThe dynein subunit consists of at least two heavy chains and a number of intermediate and light chains. The 380 kDa motor unit of dynein belongs to the AAA class of chaperone-like ATPases. The core of the 380 kDa motor unit contains a concatenated chain of six AAA modules, of which four correspond to the ATP binding sites with P-loop signatures ...
