WebJul 2, 2024 · Abstract. 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.
WebFeb 6, 2009 · Motor proteins, such as dynein, use chemical energy from ATP hydrolysis to move along the cytoskeleton. Roberts et al. (2009) now describe the arrangement of subdomains in the motor domain of dynein and propose a model for how these regions function together in force generation. ...

WebDec 12, 2008 · Dynein motors move various cargos along microtubules within the cytoplasm and power the beating of cilia and flagella. An unusual feature of dynein is that its microtubule-binding domain (MTBD) is separated from its ring-shaped AAA+ adenosine triphosphatase (ATPase) domain by a 15-nanometer coiled-coil stalk. We report the … WebJun 13, 2024 · Dyneins are motor proteins responsible for transport in the cytoplasm and the beating of axonemes in cilia and flagella.
