General annotation (Comments)

Function	Structural component of flagellum, the bacterial motility apparatus. Part of the rod structure of flagellar basal body By similarity.
Subunit structure	The basal body constitutes a major portion of the flagellar organelle and consists of a number of rings mounted on a central rod. In Gram-negative bacteria, at least four rings, L, P, S and M are present, whereas Gram-positive bacteria lack the L and P rings. The rod consists of about 26 subunits of FlgG in the distal portion, and FlgB, FlgC and FlgF build up the proximal portion of the rod with about 6 subunits each. Rod assembly occurs by export via the flagellum-specific pathway of its constituent proteins and by their incorporation into the rod structure in the probable order of FlgB, FlgC, FlgF and FlgG. Another protein, FliE, also assembles onto the stable rod structure By similarity.
Subcellular location	Bacterial flagellum basal body By similarity.
Sequence similarities	Belongs to the flagella basal body rod proteins family.
Sequence caution	The sequence BAB13042.1 differs from that shown. Reason: Frameshift at position 21.
