Dynein - an overview ScienceDirect Topics

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 these functions rely on dynein's ability to move towards the minus-end of the … WebThe nine outer pairs are made up of motor proteins called dynein.

WebToshiki Yagi, in Methods in Cell Biology, 2009. I Introduction. Dynein complexes consist of one, two, or three dynein heavy chains (DHCs) and a variety of smaller subunits. The large DHC (4000–5000 amino acids) is organized into two domains: the N-terminal tail and the C-terminal motor domain. The tail domain binds most of the smaller ... WebAug 23, 2024 · Axonemal dynein are the motor proteins that produce the beating motion within cilia and flagella. Each dynein molecule constructs a bridge between adjacent microtubules in the axoneme structure.

Webdynein - a microtubule-dependent motor protein; cytoplasmic dyneins work in organelle transport and mitosis, whereas the closely related ciliary dyneins are attatched to outer doublet microtubules in a cilium or flagellum, providing sliding/bending force used in (for example) sperm propulsion. WebThe different dynein complexes hydrolyze MgATP at different rates, for example, the microtubule stimulated ATPase activity of bovine brain cytoplasmic dynein is 0.3 mol min −1 mg −1 and the activity of axonemal outer arm dynein is 2.0 mol min −1 mg −1.Different dynein complexes also move along microtubules at different rates.
