WebMay 22, 2024 · Cytoplasmic dynein-2 powers retrograde intraflagellar transport that is essential for cilium formation and maintenance. Inactivation of dynein-2 by mutations in DYNC2H1 causes skeletal dysplasias, and it remains unclear how the dynein-2 heavy chain moves in cilia. Here, using the genome-editing technique to produce fluorescent dynein … WebFeb 1, 2013 · Summary. Dyneins are motor proteins that move along microtubules. They have many roles in the cell. They drive the beating of cilia and flagella, move cargos in the cytoplasm and function in the mitotic spindle. Dyneins are large and complex protein machines. Until recently, the way they move was poorly understood. In 2012, two high … WebATP, dynein motor proteins, and microtubule tracks are essential for movement of eukaryotic cilia and flagella.

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.

"Webfamily motors that have been studied move toward the plus-end of the microtubules [1,2,11], and thus kinesin-mediated transport is usually used to bring cargos toward the cell periphery. In contrast, dynein moves in the other direction — toward the microtubule minus-end [1,2,12] — and is typically used to move " - Dynein moves in which direction
