CC   -!- FUNCTION: Small-conductance mechanosensitive channel that opens in
CC       response to stretch forces in the membrane lipid bilayer. Exhibits a
CC       sixfold preference for cations over anions. Non-rectifying.
CC       {ECO:0000269|PubMed:11159397}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:11159397};
CC       Multi-pass membrane protein {ECO:0000269|PubMed:11159397}.
CC   -!- SIMILARITY: Belongs to the MscS (TC 1.A.23) family. {ECO:0000305}.
