"description": [
"Pore-forming subunit of the mechanosensitive non-specific cation Piezo channel required for rapidly adapting mechanically activated (MA) currents and has a key role in sensing touch and tactile pain (PubMed:20813920, PubMed:24717433, PubMed:31435011, PubMed:37590348). Piezo channels are homotrimeric three-blade propeller-shaped structures that utilize a cap-motion and plug-and-latch mechanism to gate their ion-conducting pathways (PubMed:31435011, PubMed:37590348). Expressed in sensory neurons, is essential for diverse physiological processes, including respiratory control, systemic metabolism, urinary function, and proprioception (PubMed:26551544, PubMed:28002412, PubMed:33057202, PubMed:39919739). Mediates airway stretch sensing, enabling efficient respiration at birth and maintaining normal breathing in adults (PubMed:28002412). It regulates brown and beige adipose tissue morphology and function, preventing systemic hypermetabolism (PubMed:39919739). In the lower urinary tract, acts as a sensor in both the bladder urothelium and innervating sensory neurons and is required for bladder-stretch sensing and urethral micturition reflexes, ensuring proper urinary function (PubMed:33057202). Additionally, Piezo2 serves as the principal mechanotransducer in proprioceptors, facilitating proprioception and coordinated body movements (PubMed:26551544). In inner ear hair cells, PIEZO1/2 subunits may constitute part of the mechanotransducer (MET) non-selective cation channel complex where they may act as pore-forming ion-conducting component in the complex (PubMed:38228630). Required for Merkel-cell mechanotransduction (PubMed:24717433). Plays a major role in light-touch mechanosensation (PubMed:25471886)"
