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}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:KTD51394.1}.
