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}.
