CC   -!- FUNCTION: Required for the morphogenesis and for the elongation of the
CC       flagellar filament by facilitating polymerization of the flagellin
CC       monomers at the tip of growing filament. Forms a capping structure,
CC       which prevents flagellin subunits (transported through the central
CC       channel of the flagellum) from leaking out without polymerization at
CC       the distal end (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homopentamer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted. Bacterial flagellum.
CC   -!- SIMILARITY: Belongs to the FliD family. {ECO:0000305}.
