Flagellins are a family of proteins present in flagellated bacteria which arrange themselves in a hollow cylinder to form the filament in a bacterial flagellum. Flagellin has a mass on average of about 40,000 daltons. Flagellins are the principal component of bacterial flagella that have a crucial role in bacterial motility.
The gene that encodes for flagellin has a different name in different bacterial species such as flaA (Helicobacter pylori for example), fliC, fljB.
