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.
