Touch-Sensitive Channel

Touching stretches cell membranes, opening mechanosensitive ion channels, leading to sensation. Pictured is the transmembrane region of a similar channel in bacteria. When closed, the narrow opening is lined by hydrophobic amino acid sidechains, making it non-conductive to ions.
