Mini cargo transporters on a rat run: New insight on molecular motor movement

Kinesins assume a vital function in our cells: The tiny cargo transporters move important substances along lengthy protein fibers and ensure an effective transportation infrastructure. Biophysicists of the Technische Universitaet Muenchen and the Ludwig Maximillians Universitaet Muenchen have now discovered how some of these transporters can, like cars on a multi-lane motorway, change lanes. The researchers report on this hitherto unknown phenomenon in the current edition of the renowned journal Molecular Cell.
