CC   -!- FUNCTION: Required for 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. {ECO:0000256|RuleBase:RU362066}.
CC   -!- SUBUNIT: Homopentamer. {ECO:0000256|ARBA:ARBA00011255,
CC       ECO:0000256|RuleBase:RU362066}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000256|RuleBase:RU362066}.
CC       Bacterial flagellum {ECO:0000256|RuleBase:RU362066}.
CC   -!- SIMILARITY: Belongs to the FliD family. {ECO:0000256|ARBA:ARBA00009764,
CC       ECO:0000256|RuleBase:RU362066}.
