چکیده

Dynein is an AAA+ (ATPase associated with various cellular activities)-type motor complex that utilizes ATP hydrolysis to actively drive microtubule sliding. The dynein heavy chain (molecular mass >500 kDa) contains six tandemly linked AAA+ modules and exhibits full motor activities. Detailed molecular dissection of this motor with unique architecture was hampered by the lack of an expression system for the recombinant heavy chain, as a result of its large size. However, the recent success of recombinant protein expression with full motor activities has provided a method for advances in structure-function studies in order to elucidate the molecular mechanism of force generation.

A structural model reveals energy transduction in dynein.

Intracellular active transport is driven by ATP-hydrolyzing motor proteins that move along cytoskeletal filaments. In particular, the microtubule-associated dynein motor is involved in the transport of organelles and vesicles, the maintenance of the Golgi, and mitosis. However, unlike kinesin and myosin, the mechanism by which dynein converts chemical energy into mechanical force remains largel...

The third P-loop domain in cytoplasmic dynein heavy chain is essential for dynein motor function and ATP-sensitive microtubule binding.

Sequence comparisons and structural analyses show that the dynein heavy chain motor subunit is related to the AAA family of chaperone-like ATPases. The core structure of the dynein motor unit derives from the assembly of six AAA domains into a hexameric ring. In dynein, the first four AAA domains contain consensus nucleotide triphosphate-binding motifs, or P-loops. The recent structural models ...

A structural analysis of the AAA+ domains in Saccharomyces cerevisiae cytoplasmic dynein

Dyneins are large protein complexes that act as microtubule based molecular motors. The dynein heavy chain contains a motor domain which is a member of the AAA+ protein family (ATPases Associated with diverse cellular Activities). Proteins of the AAA+ family show a diverse range of functionalities, but share a related core AAA+ domain, which often assembles into hexameric rings. Dynein is unusu...

Big steps toward understanding dynein

It has been 50 years since dynein was discovered and named by Ian Gibbons as a motor protein that drives cilia/flagella bending (Gibbons, 1963; Gibbons and Rowe, 1965). In the mid-1980s, dynein was also found to power retrograde transport in neurons (Paschal and Vallee, 1987). Subsequently, the primary amino acid sequence of the cytoplasmic dynein heavy chain, which contains the motor domain, w...

Molecular dissection of the roles of nucleotide binding and hydrolysis in dynein's AAA domains in Saccharomyces cerevisiae.

The motor protein cytoplasmic dynein is responsible for most of the minus-end-directed microtubule traffic within cells. Dynein contains four evolutionarily conserved AAA (ATPase associated with various cellular activities) domains that are thought to bind nucleotide; the role of nucleotide binding and hydrolysis in each of these four AAA domains has constituted an important and unresolved ques...
