WebTalk Overview. In an interview with Ron Vale, Ian Gibbons describes how his initial chemical dissection of the internal structure of Tetrahymena cilia led him to seek and then identify the force-producing ATPase, which he named dynein. Gibbons also describes his key experiment showing that dynein produces sliding between microtubules, which ...
WebApr 11, 2024 · In structures like the trachea, bronchial tubes, and nasal cavities, the ciliated epithelium is responsible for transporting particles or fluid over the epithelial surface. It frequently appears near mucus-secreting goblet cells. Cilia are tiny hair-like protuberances on the exterior of eukaryotic cells (or cilia in plural). WebA simplified model of intraflagellar transport. An axoneme, also called an axial filament is the microtubule -based cytoskeletal structure that forms the core of a cilium or flagellum.

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. WebDyneins are classified as either cytoplasmic or flagellar, and the flagellar dyneins are further divided into the outer arm and inner arm dyneins. Cytoplasmic dynein moves …

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.
