Key component of innate and adaptive immunity. TLRs (Toll-like receptors) control host immune response against pathogens through recognition of molecular patterns specific of 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.
Specificity
Natural and recombinant Bovine Toll-like receptor 3
Subcellular Location
Endoplasmic reticulum membrane Single-pass type I membrane protein Endosome membrane
Binds MYD88 via their respective TIR domains. 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. Interacts (via transmembrane domain) with UNC93B1.
