UniProt functional annotation for Q9WY63

UniProt code: Q9WY63.

Organism: Thermotoga maritima (strain ATCC 43589 / DSM 3109 / JCM 10099 / NBRC 100826 / MSB8).
Taxonomy: Bacteria; Thermotogae; Thermotogales; Thermotogaceae; Thermotoga.
 
Function: One of the proteins that forms a switch complex that is proposed to be located at the base of the basal body. This complex interacts with chemotaxis proteins (such as CheY) in addition to contacting components of the motor that determine the direction of flagellar rotation (By similarity). {ECO:0000250}.
 
Subunit: Homodimer in the absence of FliF. Interacts (via N-terminus) with FliF (via C-terminus) forming a heterodimer. Interacts (via central domain or via central domain and C-terminus) with FliM (via central domain). {ECO:0000269|PubMed:21673656, ECO:0000269|PubMed:22670715, ECO:0000269|PubMed:22896702}.
Subcellular location: Cell inner membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}; Cytoplasmic side {ECO:0000250}. Bacterial flagellum basal body {ECO:0000250}.
Similarity: Belongs to the FliG family. {ECO:0000305}.
