| Description | Dyneins are described as motor proteins of eukaryotic cells, as they can convert energy derived from the hydrolysis of ATP to force and movement along cytoskeletal polymers, such as microtubules. Dyneins generally contain one to three heavy chains, which belong to the AAA+ superfamily of mechanochemical enzymes [ ]. Each heavy chain consists of a flexible N-terminal tail known as the cargo-binding domain [] and a motor domain which consists of an ATP-hydrolysing AAA+ ring, a flexible microtubule-binding stalk, a linker and a C-sequence []. The stalk has an ATP-sensitive microtubule-binding site (MTBD) at its tip [, ], whereas the linker has been suggested to function as a mechanical element for generating dynein's power stroke [, , ].The two categories of dyneins are the axonemal dyneins, which produce the bending motions that propagate along cilia and flagella, and the cytosolic dyneins, which drive a variety of fundamental cellular processes including nuclear migration, organisation of the mitotic spindle, chromosome separation during mitosis, and the positioning and function of many intracellular organelles. Cytoplasmic dyneins contain several accessory subunits ranging from light to intermediate chains.This superfamily represents the N-terminal part of the second domain of dynein heavy chain. No function seems to have been attributed specifically to this region. |
