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 membrane {ECO:0000255|HAMAP-Rule:MF_00115};
CC       Multi-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_00115}.
CC   -!- SIMILARITY: Belongs to the MscL family. {ECO:0000255|HAMAP-
CC       Rule:MF_00115}.
