A toddler running sometimes loses footing because both feet come off the ground at the same time. Kinesin motors that move materials around in cells have the same problem, which limits how fast they can traverse a microtubule ...
Imagine a liquid that could move on its own. No need for human effort or the pull of gravity. You could put it in a container flat on a table, not touch it in any way, and it would still flow.
Inside mammalian cells, kinesin plays the same role as do trucks and locomotives within our countries: It is the main driving force behind the transport of manufactured goods. No wheels are involved, but there are 'legs' ...
Using a succession of biological mechanisms, Sandia National Laboratories researchers have created linkages of polymer nanotubes that resemble the structure of a nerve, with many out-thrust filaments poised to gather or send ...
Tiny protein motors in cells can steer microtubules in the right direction through branching nerve cell structures, according to Penn State researchers who used laboratory experiments to test a model of how these cellular ...
Rice University researchers have engineered cells to characterize how sensitively altering the cooperative functions of motor proteins can regulate the transport of organelles.
(Phys.org) —Molecular motor proteins inside the body, called kinesins, are a lot like the motor in your car. The molecular motors convert stored chemical energy into specific conformational changes, which lead to various ...
Researchers at UC San Diego’s Department of Chemistry and Biochemistry, in collaboration with several universities in the U.S., United Kingdom, and Poland, have developed a new picture of how kinesin molecules move along ...
(PhysOrg.com) -- Life's smallest motor, a protein that shuttles cargo within cells and helps cells divide, does so by rocking up and down like a seesaw, according to research conducted by scientists at the U.S. Department ...
In the fruit fly Drosophila, oskar mRNA, which is involved in defining the animal’s body axes, is produced in the nuclei of nurse cells neighbouring the oocyte, and must be transported to the oocyte and along its entire ...
