CC   -!- FUNCTION: Flagellin is the subunit protein which polymerizes to form
CC       the filaments of bacterial flagella. Important for motility and
CC       virulence (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Heteromer of FlaA and FlaB. FlaB is located proximal to the
CC       hook while the remainder of the filament is composed of the predominant
CC       FlaA (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}. Bacterial flagellum
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the bacterial flagellin family. {ECO:0000305}.
