Dynein molecular weight
WebAug 8, 2024 · Cytoplasmic dynein-1 (referred to here as ‘dynein-1’) was first isolated as a high-molecular weight ATPase (adenosine 5′-triphosphatase) with biochemical, structural, and motile properties distinct from those of kinesin; the motor driving movement to microtubule plus ends [5,6]. Since then, it has emerged that dynein-1 powers the minus ... WebNov 1, 2006 · The dynein family at a glance. J Cell Sci (2006) 119 (21): 4369–4371. Three families of cytoskeletal motor protein – the myosins, kinesins and dyneins – have evolved to mediate transport of cells and of structures and materials within cells in eukaryotes. Whereas myosin uses actin polymers to carry out its tasks, kinesin and dynein are ...
