title: Cell biology: cytoskeleton network topology feeds back on its regulation.
abstract: Many cell functions rely on microtubule dynamics and ordering. Two recent studies show that microtubule severing by katanin plays an overbearing role in this process and is primarily regulated at microtubule crossovers.
