WebFeb 4, 2024 · In vitro motility assays clearly indicate that cytoplasmic dynein and kinesin can function independently to produce motility in opposite directions along microtubules, but multiple studies have also suggested that the activities of these two motors are coordinately coupled in the cell [Citation 24]; thus, these two motors may lead to the ... WebApr 17, 2024 · If dynein-mediated cargo movement was generally disrupted, other cargos, including lysosomes and dynein itself, would fail to move in the retrograde direction as well. Second, the axonal phenotype of dynactin and dynein loss-of-function mutants is vastly different from actr10 mutants: dync1h1 and p150a/b mutants display pLL nerve …

WebSep 3, 2013 · Although dynein is known to carry certain cargoes through regions outside its motor domain, how it transports other microtubules is not well understood. ... Inside the overlap, dynein often pauses and switches directions, suggesting the motor spends a fraction of time stepping with both motor domains on a single MT in the overlap, and … Dyneins are a family of cytoskeletal motor proteins that move along microtubules in cells. They convert the chemical energy stored in ATP to mechanical work. Dynein transports various cellular cargos, provides forces and displacements important in mitosis, and drives the beat of eukaryotic cilia and flagella. All of … See more Axonemal dynein causes sliding of microtubules in the axonemes of cilia and flagella and is found only in cells that have those structures.
