Protonation of the Human PIEZO1 Ion Channel Stabilizes Inactivation
PIEZO1 is a recently cloned eukaryotic cation-selective channel that opens with mechanical force. We found that extracellular protonation inhibits channel activation by ≈90% by increased occupancy in the closed or the inactivated state. Titration between pH 6.3 and 8.3 exhibited a pK of ≈6.9. The st...
