title: Aha, another regulator for hsp90 chaperones.
abstract: A large number of key regulators controlling homeostasis and cell fate are chaperoned by the Hsp90 folding machine. In this issue of Molecular Cell, report the discovery of a new stress-regulated cochaperone, Aha1, which accelerates the dynamics of this machine.
