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 ...

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 ...

Motor proteins are molecular machines that convert the chemical energy derived from the hydrolysis of ATP into mechanical work used to power cellular motility. In addition to specialized motile cells like muscle fibers and cellular processes like cilia, all eukaryotic cells contain motor proteins (Fig. 1).

Mutational Analysis of Motor Proteins
Annual Review of Physiology, 1996Mutations in motor proteins, which can arise by design or randomly, provide powerful insights into the normal function of the protein. This review organizes the available data on mutations of members of the myosin, kinesin, and dynein superfamilies of motor proteins.

Chromatin folding through nonuniform motorization by responsive motor proteins
The Journal of Chemical PhysicsChromatin is partially structured through the effects of biological motors. “Swimming motors” such as RNA polymerases and chromatin remodelers are thought to act differentially on the active parts of the genome and the stored inactive part. By systematically expanding the many-body master equation for chromosomes driven by swimming motors, we show that

The cell skeleton forms a scaffold, along which motor proteins can move. These proteins convert the chemical energy of ATP-hydrolysis into mechanical energy. Movement is unidirectional, either from minus to plus or vice versa. The most important systems are microfilament /myosin and microtubule /kinesin and -dynamin .

Motor proteins for cytoplasmic microtubules
Current Opinion in Cell Biology, 1992It has been thought that motile structures within the cell are driven toward the plus and minus ends of microtubules by the ATPases, kinesin and dynein, respectively. Recently obtained data indicate that this model is far too simplistic. Kinesin is now understood to be one representative of a family of proteins. Another member of the kinesin family has

Non-motor microtubule-associated proteins
Current Opinion in Cell Biology, 1993This past year, the structure and function of microtubule-associated proteins (MAPs) have been investigated in studies probing their phosphorylation, patterns of expression, and the function of the microtubule-binding domain. Cellular studies have also contributed new insights into the roles of these proteins in process outgrowth.
