WebSep 9, 2024 · Kinesin-1 and cytoplasmic dynein are microtubule (MT) motors that transport intracellular cargoes. 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.

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.
