Fungal heat shock protein 90 (Hsp90) is an essential chaperone that regulates a range of cellular processes by ensuring the correct folding of a specific group of client proteins. In this Review, Brown and colleagues describe the roles and regulation of Hsp90 and discuss how it acts as a biological transistor to modulate fungal signalling networks.
