WebApr 26, 2024 · Dynein 6 and kinesin 7 are microtubule (MT)-based, motile, motor proteins that transport cellular cargos, including viruses. 6, 8-11 They use the chemical energy from the hydrolysis of adenosine triphosphate (ATP) for their mechanical motions. As dynein interacts with the cytoskeletal protein MT, it moves from the cell periphery toward the … WebJun 13, 2024 · Dyneins are motor proteins responsible for transport in the cytoplasm and the beating of axonemes in cilia and flagella. They bind and release microtubules via a compact microtubule-binding domain (MTBD) at the end of a coiled-coil stalk. We address how cytoplasmic and axonemal dynein MTBDs bind microtubules at near atomic resolution. WebProteins are the prime example of self-organized networks, as they have benefited from extensive natural (Darwinian) selection. Here, we quantify the dynamical shapes of dynein as they have evolved through interactions with water films.
