CC   -!- FUNCTION: Required for formation of the rod structure in the basal body
CC       of the flagellar apparatus. Together with FliI and FliH, may constitute
CC       the export apparatus of flagellin (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the type III secretion exporter family.
CC       {ECO:0000305}.
