== Function ==
[https://www.uniprot.org/uniprot/FLIN_SALTY FLIN_SALTY] 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).

== Publication Abstract from PubMed ==
Translocating proteins across the double membrane of Gram-negative bacteria, type III secretion systems (T3SS) occur in two evolutionarily related forms: injectisomes, delivering virulence factors into host cells, and the flagellar system, secreting the polymeric filament used for motility. While both systems share related elements of a cytoplasmic sorting platform that facilitates the hierarchical secretion of protein substrates, its assembly and regulation remain unclear. Here we describe a module mediating the assembly of the sorting platform in both secretion systems, and elucidate the structural basis for segregation of homologous components among these divergent T3SS subtypes sharing a common cytoplasmic milieu. These results provide a foundation for the subtype-specific assembly of T3SS sorting platforms and will support further mechanistic analysis and anti-virulence drug design.

A common assembly module in injectisome and flagellar type III secretion sorting platforms.,Notti RQ, Bhattacharya S, Lilic M, Stebbins CE Nat Commun. 2015 May 21;6:7125. doi: 10.1038/ncomms8125. PMID:25994170<ref>PMID:25994170</ref>
