CC   -!- FUNCTION: Mechanosensitive channel that participates in the regulation
CC       of osmotic pressure changes within the cell, opening in response to
CC       stretch forces in the membrane lipid bilayer, without the need for
CC       other proteins. Contributes to normal resistance to hypoosmotic shock.
CC       Forms an ion channel of 1.0 nanosiemens conductance with a slight
CC       preference for anions. The channel is sensitive to voltage; as the
CC       membrane is depolarized, less tension is required to open the channel
CC       and vice versa. The channel is characterized by short bursts of
CC       activity that last for a few seconds. {ECO:0000250|UniProtKB:P0C0S1}.
CC   -!- SUBUNIT: Homoheptamer. {ECO:0000250|UniProtKB:P0C0S1}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane
CC       {ECO:0000250|UniProtKB:P0C0S1}; Multi-pass membrane protein
CC       {ECO:0000250|UniProtKB:P0C0S1}.
CC   -!- SIMILARITY: Belongs to the MscS (TC 1.A.23) family. {ECO:0000305}.
