WebDynein Axonemal Light Chain 4 (DNAL4) protein is understood to be part of the axonemal (or ciliary and flagellar) complex of dynein molecules (including dynein heavy and light chains) (GO:0005858) and a component of the microtubule-based dynein motor complex [13].In humans, two known axonemal light chain proteins, DNAL1 and DNAL4, sit at the … WebStructural overview of a dynein dimer. The two dynein motor domains, which are dimerized by GST, are related by a pseudo-two-fold symmetry, such that the linker-face of the AAA rings appose each other and the stalk domains point in opposite directions (Fig. 1B). The presence of the linker domain makes it unlikely that the two AAA rings can directly crystal light blackberry lemonade

Structure and Functional Role of Dynein

WebDynein is a motor protein (also called molecular motor or motor molecule) in cells which converts the chemical energy contained in ATP into the mechanical energy of movement. ... Each heavy chain has a globular motor domain with a doughnut-shaped structure believed to resemble that of other AAA proteins, a coiled coil "stalk" that binds to the ... WebDec 26, 2007 · Cytoplasmic dynein is a large protein complex (1.2 MDa) composed of two identical heavy chains (<500 kDa) and several intermediate and light chains ().The heavy chain has three functionally distinct domains (): a globular head with ATPase activity, a cargo-binding tail, and a microtubule-binding stalk.The tail is formed by the N terminus … dwnwhitechapel.comWebFeb 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. ...
