Description
PIEZO2 (Piezo-type mechanosensitive ion channel component 2), also called Protein FAM38B, is a transmembrane protein that spans the cell membrane and acts as a sensor for mechanical stimuli. When external forces, such as touch or pressure, are applied to the cell membrane, PIEZO2 responds by opening up and allowing ions to flow into the cell. This influx of ions triggers a signal that is transmitted to the brain, allowing us to perceive and respond to the touch sensation. It also plays a critical role in a variety of other sensory functions, including proprioception (the ability to sense the position of our body in space) and hearing. Recent studies have uncovered even more functions of PIEZO2 beyond sensory perception. It has been found to be involved in regulating lung development, bone formation, and even cell migration
