Motor proteins in cell division
Trends in Cell Biology, 1991The movements of eukaryotic cell division depend upon the conversion of chemical energy into mechanical work, which in turn involves the actions of motor proteins, molecular transducers that generate force and motion relative cytoskeletal elements. In animal cells, microtubule-based motor proteins of the mitotic apparatus are involved in segregating ...

Mechanisms of motor protein reversal
Current Opinion in Cell Biology, 2001Members of the kinesin superfamily of microtubule-based motors and the myosin superfamily of actin-based motors that move 'backwards' have been identified. As the core catalytic domains of myosins and kinesins are similar in structure, this raises the intriguing questions of how direction reversal is accomplished and whether kinesins and myosins share ...

The protein import motor of mitochondria
Nature Reviews Molecular Cell Biology, 2002Proteins that are destined for the matrix of mitochondria are transported into this organelle by two translocases: the TOM complex, which transports proteins across the outer mitochondrial membrane; and the TIM23 complex, which gets them through the inner mitochondrial membrane. Two models have been proposed to explain how this protein-import machinery

Microtubule-based motor proteins
Current Opinion in Cell Biology, 1990Virtually all eukaryotes actively transport or position intracellular components (for example, chromosomes or membrane-bounded organelles), and some cells have developed means of moving through aqueous environments or on top of substrates. Such motile processes invob,'ed interactions between cytoskeletal fibers and 'motor' proteins that generate force ...

Regulation of molecular motor proteins
2001Motor proteins in the kinesin, dynein, and myosin superfamilies are tightly regulated to perform multiple functions in the cell requiring force generation. Although motor proteins within families are diverse in sequence and structure, there are general mechanisms by which they are regulated.

The structure of microtubule motor proteins
2005Microtubules are the intracellular tracks for two classes of motor proteins: kinesins and dyneins. During the past few years, the motor domain structures of several kinesins from different organisms have been determined by X-ray crystallography. Compared with kinesins, dyneins are much larger proteins and attempts to crystallize them have failed so far.

Protein profile, 1996
Progress regarding the kinesins is now being made at a rapid and accelerating rate. The in vivo-functions, and biophysical and enzymatic properties of kinesin itself are being explored at ever increasing levels of detail. The kinesin-related proteins now number several dozen, and although more is known about primary structure than function for most of ...
