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. TLR3 is a nucleotide-sensing TLR which is activated by double-stranded RNA, a sign of viral infection. 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 (via transmembrane domain) with UNC93B1 (By similarity). Interacts with TICAM1. Homodimer formation is triggered by ligand binding and is required for TLR3 signaling. Binding of double- stranded RNA is required for the interaction with SRC. SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Single-pass type I membrane protein. Endosome membrane. TISSUE SPECIFICITY: Expressed at high level in placenta and pancreas. Also detected in CD11c+ immature dendritic cells. Only expressed in dendritic cells and not in other leukocytes, including monocyte precursors. TLR3 is the TLR that is expressed most strongly in the brain, especially in astrocytes, glia, and neurons. DOMAIN: ds-RNA binding is mediated by LRR 1 to 3, and LRR 17 to 18 (By similarity). PTM: Heavily N-glycosylated, except on that part of the surface of the ectodomain that is involved in ligand binding. DISEASE: Defects in TLR3 are associated with herpes simplex encephalitis type 2 (HSE2) [MIM:613002]. HSE is a rare complication of human herpesvirus 1 (HHV-1) infection, occurring in only a small minority of HHV-1 infected individuals. HSE is characterized by hemorrhagic necrosis of parts of the temporal and frontal lobes. Onset is over several days and involves fever, headache, seizures, stupor, and often coma, frequently with a fatal outcome. Note=TLR3 mutations predispose otherwise healthy individuals to isolated herpes simplex encephalitis through a mechanism that involves impaired IFNs production and reduced immune defense against viral infection in the central nervous system. SIMILARITY: Belongs to the Toll-like receptor family. SIMILARITY: Contains 22 LRR (leucine-rich) repeats. SIMILARITY: Contains 1 LRRCT domain. SIMILARITY: Contains 1 LRRNT domain. SIMILARITY: Contains 1 TIR domain. WEB RESOURCE: Name=TLR3base; Note=TLR3 mutation db; URL="http://bioinf.uta.fi/TLR3base/"; GENE SYNONYMS:TLR3.
