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. {ECO:0000256|RuleBase:RU369025}. CC -!- SUBUNIT: Homoheptamer. {ECO:0000256|RuleBase:RU369025}. CC -!- SUBCELLULAR LOCATION: Cell inner membrane CC {ECO:0000256|RuleBase:RU369025}; Multi-pass membrane protein CC {ECO:0000256|RuleBase:RU369025}. Membrane CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein CC {ECO:0000256|ARBA:ARBA00004141}. CC -!- SIMILARITY: Belongs to the MscS (TC 1.A.23) family. CC {ECO:0000256|ARBA:ARBA00008017, ECO:0000256|RuleBase:RU369025}. CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of CC feature annotation. {ECO:0000256|RuleBase:RU369025}.
