CC   -!- FUNCTION: FliM is one of 2 proteins (FliG, FliN) that might form a
CC       switch complex that is proposed to be located at the base of the basal
CC       body. This complex interacts with the CheY and CheZ chemotaxis
CC       proteins, in addition to contacting components of the motor that
CC       determine the direction of flagellar rotation (Potential).
CC       {ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000305}; Peripheral
CC       membrane protein {ECO:0000305}; Cytoplasmic side {ECO:0000305}.
CC       Bacterial flagellum basal body {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the FliN/MopA/SpaO family. {ECO:0000305}.
