CC   -!- FUNCTION: Channel that opens in response to stretch forces in the
CC       membrane lipid bilayer. May participate in the regulation of osmotic
CC       pressure changes within the cell. {ECO:0000255|HAMAP-Rule:MF_00115}.
CC   -!- SUBUNIT: Homopentamer. {ECO:0000255|HAMAP-Rule:MF_00115}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00115}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00115}.
CC   -!- SIMILARITY: Belongs to the MscL family. {ECO:0000255|HAMAP-
CC       Rule:MF_00115}.
