WebAug 4, 2011 · Cytoplasmic dynein is a microtubule (MT) motor protein comprising two classes: dynein-1 and dynein-2. We purified recombinant human dynein-1 and dynein-2 from HEK-293 cells by expressing the streptavidin-binding peptide-tagged human cytoplasmic dynein-1 and dynein-2 heavy chains (HCs), respectively. … WebDynein complexes are composed of one, two, or three heavy chains, and each complex has various smaller accessory subunits (Tables I and II). Cytoplasmic dynein has two … shy and flo viadukt
