Dynein moves in which direction

Webfamily motors that have been studied move toward the plus-end of the microtubules [1,2,11], and thus kinesin-mediated transport is usually used to bring cargos toward the cell periphery. In contrast, dynein moves in the other direction — toward the microtubule minus-end [1,2,12] — and is typically used to move WebFeb 26, 2024 · Dynein, one of three cytoskeletal motor protein families, was first identified a half century ago and got its name after the ‘dyne’ (i.e. a unit of force). Motor proteins are …

WebFeb 1, 2013 · Summary. Dyneins are motor proteins that move along microtubules. They have many roles in the cell. They drive the beating of cilia and flagella, move cargos in the cytoplasm and function in the mitotic spindle. Dyneins are large and complex protein machines. Until recently, the way they move was poorly understood. In 2012, two high … Webdyneins bind and move in the opposite direction, back to the cell body of the neuron.
