WebDec 21, 2024 · What is dynein. Dynein is a type of motor protein that uses microtubules in the cytoskeleton to carry its cargo. It's kind of a big motor protein. Since it carries its cargo to the minus end of the microtubules, dynein is also known as minus-end-directed motor proteins. That means; Dynein transports cargo from the periphery to the center of the ...

It remains unclear how these motors move along MTs densely coated with obstacles of various sizes in the cytoplasm. Here, we tested the ability of single and multiple motors to bypass synthetic obstacles on MTs in vitro.
WebApr 27, 2024 · According to the Markus lab’s new study, published April 27 in Nature Cell Biology, the exact opposite is true: Lis1 activates dynein, working to wedge itself in such a way that the motor protein is prevented from folding itself into an “off” state – inhibiting its ability to auto-inhibit, the researchers explain.

WebStephen M. King, in Dyneins: Structure, Biology and Disease (Second Edition), 2024 Abstract. Axonemal dyneins form the inner and outer arms that are associated with doublet microtubules within cilia and flagella. These enzymes provide the motive force necessary for ciliary/flagellar beating by driving the sliding of microtubules with respect to each other.
