CC   -!- FUNCTION: FliG 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 (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Peripheral
CC       membrane protein {ECO:0000250}; Cytoplasmic side {ECO:0000250}.
CC       Bacterial flagellum basal body {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the FliG family. {ECO:0000305}.
