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.

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.

Non-motor microtubule-associated proteins
Current Opinion in Cell Biology, 1991Cloning of primary sequences has generated information on the structures of the non-motor microtubule-associated proteins and their relationship to one another. Questions about how classes of microtubule-associated proteins interact are starting to be addressed in vitro and, in vivo, tests of function are being pursued using a variety of cellular and ...
