UniProtKB description:  Mechanosensitive cation channel with low conductance and high activation threshold. Essential for the baby's first breath and respiration throughout life. Upon lung inflation conducts cation currents in alveolar type 1 and 2 cells triggering lamellar body exocytosis and surfactant secretion into airspace (PubMed:30382938, PubMed:37543036, PubMed:38127458). Osmosensitive cation channel preferentially activated by hypotonic stress. Acts as an osmosensor in cochlear outer hair cells (OHCs) where it mediates calcium influx and regulatory volume decrease response. Required for the maintenance of OHC morphology, OHC survival and normal hearing (PubMed:27045885, PubMed:31243992, PubMed:32375046, PubMed:37543036, PubMed:37945568).
