CC   -!- FUNCTION: FliM is one of three proteins (FliG, FliN, FliM) that forms
CC       the rotor-mounted switch complex (C ring), located at the base of the
CC       basal 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.
CC   -!- SUBUNIT: Interacts with flagellar brake protein YcgR.
CC       {ECO:0000269|PubMed:20346719}.
CC   -!- INTERACTION:

CC   -!- SUBCELLULAR LOCATION: Cell inner membrane; Peripheral membrane protein.
CC       Bacterial flagellum basal body.
CC   -!- SIMILARITY: Belongs to the FliM family. {ECO:0000305}.
