Dartmouth researchers find new protein function
A group of Dartmouth researchers has found a new function for one of the proteins involved with chromosome segregation during cell division. Their finding adds to the growing knowledge about the...

(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...
View ArticleA metal switch to control motor proteins
(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,...
View ArticleSome motor proteins cooperate better than others
Rice University researchers have engineered cells to characterize how sensitively altering the cooperative functions of motor proteins can regulate the transport of organelles.
View ArticleExperiments show hypothesis of microtubule steering accurate
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...
