Prestin is an anion transporter-like protein in the mammalian inner ear that amplifies sound-induced vibration by voltage-driven structural rearrangements. Here, Gorbunov et al. show that this electromechanical activity is controlled by the binding of anions to a central cavity within the protein core.
