flagellin

 [flaj´ĕ-lin]
a protein (mol. wt. approximately 40,000) occurring in the flagella of bacteria, which is composed of subunits arranged in several-stranded helix formation somewhat resembling myosin in structure, and sometimes containing ε-N-methyl lysine. Its composition varies with the species; thus flagellin antibodies are species specific.

flag·el·lin

(flaj'ĕ-lin),
Any member of a class of proteins that constitue subunits of the flagella and that contain the amino acid ε-N-methyllysine.

flagellin

/fla·gel·lin/ (flah-jel´in) a protein of bacterial flagella; it is composed of subunits in several-stranded helical arrangement.

flagellin

(flə-jĕl′ĭn)
n.
Any of a group of proteins that are the structural components of bacterial flagella.

TLRs 1,2,4,5,6 and 11 are located on the plasma membrane of cells of the innate immune system and epithelial cells and recognise a range of pathogen-associated molecular patterns found on the cell-wall of bacteria, including lipopeptides (TLRs1 and 6), lipoteichoic acids and lipoproteins (TLR2), lipopolysaccharides (TLR4), and bacterial flagellin (TLR5), while TLR11 interacts with less well-defined ligands on uropathogenic bacteria; (3) the remaining TLRs are located cytoplasmically in endosomes where they interact with viral double-stranded (TLR3) and singlestranded RNA (TLRs7 and 8), and with bacterial and viral DNA via interactions with so-called unmethylated CpG sites (TLR9), which are rarely encountered on the human genome.
