Just like people, some proteins have characteristic ways of "walking," which (also like human gaits) are not so easy to describe. But now scientists have discovered the unique "drunken sailor" gait of dynein, a protein that is critical for the function of every cell in the body and whose malfunction has been associated with neurodegenerative disorders such as Lou Gehrig's disease and Parkinson's disease. The research, which was led by Samara Reck-Peterson of Harvard Medical School and...

Rice University bioengineers measure pulling power of hitched pairs of protein motors A new study by Rice University bioengineers finds that the workhorse proteins that move cargo inside living cells behave like prima donnas. The protein, called kinesin, is a two-legged molecular machine. Rice's scientists invented tools that could measure the pulling power of kinesin both singly and in pairs, and they report this week in Biophysical Journal that kinesins don't work well together -- in...

Findings shed light on brain malformation that kills infants A University of Utah researcher helped discover how a "wimpy" protein motor works with two other proteins to gain the strength necessary to move nerve cells and components inside them. The findings shed light on brain development and provide clues to a rare brain disorder that often kills babies within months of birth. "It's like the 'Transformers' films: You start with this puny little car and it becomes a big robot capable of...

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 of Energy's Lawrence Berkeley National Laboratory and Brandeis University. The researchers created high-resolution snapshots of a protein motor, called kinesin, as it walked along a microtubule, which are tube-shaped structures that form a cell's "skeleton." The result is the closest look...

An international team of scientists led by the University of Leeds has shed new light on the little-understood motor protein called dynein, thought to be involved in progressive neurological disorders such as motor neurone disease. Researchers from the University's Astbury Centre for Structural Molecular Biology and from the University of Tokyo have for the first time identified key elements of dynein's structure, and the winch-like mechanism by which it moves. The research "“ funded by...
