Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Buchnera

Protein attributes

Sequence length	133 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	FliN is one of three proteins (FliG, FliN, FliM) that form the rotor-mounted switch complex (C ring), located at the base of the basal body. This complex interacts with the CheY and CheZ chemotaxis proteins, in addition to contacting components of the motor that determine the direction of flagellar rotation By similarity.
Subcellular location	Cell membrane; Peripheral membrane protein; Cytoplasmic side By similarity. Bacterial flagellum basal body By similarity.
Sequence similarities	Belongs to the FliN/MopA/SpaO family.
