General annotation (Comments)
| 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. TLR9 is a nucleotide-sensing TLR which is activated by unmethylated cytidine-phosphate-guanosine (CpG) dinucleotides. Acts via MYD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. Controls lymphocyte response to Helicobacter infection. Ref.10 Ref.11 |
| Subunit structure | Interacts with MYD88 via their respective TIR domains By similarity. Interacts (via transmembrane domain) with UNC93B1 By similarity. Interacts with CD300LH; the interaction may promote full activation of TLR9-triggered innate responses By similarity. Interacts with BTK. Interacts with CNPY3 and HSP90B1; this interaction is required for proper folding in the endoplasmic reticulum. Ref.11 Ref.12 |
| Subcellular location | Endoplasmic reticulum membrane; Single-pass type I membrane protein By similarity. Endosome By similarity. Lysosome By similarity. Cytoplasmic vesicle › phagosome By similarity. Note: Relocalizes from endoplasmic reticulum to endosome and lysosome upon stimulation with agonist By similarity. |
| Tissue specificity | Highly expressed in spleen, lymph node, tonsil and peripheral blood leukocytes, especially in plasmacytoid pre-dendritic cells. Levels are much lower in monocytes and CD11c+ immature dendritic cells. Also detected in lung and liver. |
| Sequence similarities | Belongs to the Toll-like receptor family. Contains 26 LRR (leucine-rich) repeats. Contains 1 TIR domain. |
