Abstract

Piezos are force-gated ion channels that detect and communicate membrane tension to the cell. Recent work from Ullah, Nosyreva, and colleagues characterizes partial channel openings, known as subconductance states, and develops a new gating model of Piezo1 function.

Keywords: Piezo channels; force-gated ion channels; gating model; mechanotransduction; subconductance states.
