ID:TLR8_HUMAN DESCRIPTION: RecName: Full=Toll-like receptor 8; AltName: CD_antigen=CD288; Flags: Precursor; FUNCTION: Key component of innate and adaptive immunity. TLRs (Toll-like receptors) control host immune response against pathogens through recognition of molecular patterns specific to microorganisms. Acts via MYD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. SUBUNIT: Interacts with MYD88 via their respective TIR domains. Interacts with UNC93B1 (By similarity). Interacts with BTK. SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein (By similarity). TISSUE SPECIFICITY: Detected in brain, heart, lung, liver, placenta, in monocytes, and at lower levels in CD11c+ immature dendritic cells. SIMILARITY: Belongs to the Toll-like receptor family. SIMILARITY: Contains 23 LRR (leucine-rich) repeats. SIMILARITY: Contains 1 LRRCT domain. SIMILARITY: Contains 1 TIR domain.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
