Despite a general domain organization that is found in all the cytoskeletal motors, there are structural features of dynein that set it apart from the other motors. These include a track-binding site that is located at the tip of a long projection, …
WebDec 1, 1998 · Three classes of cytoskeletal motor protein have been identified—myosins, kinesins and dyneins. Together, these proteins are now thought to be responsible for the remarkable variety of movements that occur in eukaryotic cells and that are essential for reproduction and survival. Crystallographic analysis of the myosin and kinesin motor … 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.
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 ...

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.
