'Prima Donna' Protein Doesn't Work Well in Pairs
November 5, 2010
A new study by Rice University bioengineers finds that the workhorse proteins that move cargo inside living cells behave like prima donnas. These molecular-scale machines called kinesin, are two-legged mechanical motor proteins. Using an especially sensitive set of tools, Rice's scientists measured the pulling power of kinesin both singly and in pairs. They report this week in Biophysical Journal that kinesins don't work well together--in part because they are so effective on their own.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
