Additional Info
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.
Post Translational Modifications
Heavily N-glycosylated, except on that part of the surface of the ectodomain that is involved in ligand binding. TLR3 signaling requires a proteolytic cleavage mediated by cathepsins CTSB and CTSH, the cleavage occurs between amino acids 252 and 346. The cleaved form of TLR3 is the predominant form found in endosomes. Ubiquitinated by TRIM3.leading to recognition and sorting of polyubiquitinated TLR3 by the ESCRT complexes. Ubiquitinated by ZNRF1 via 'Lys-63'-linked ubiquitin chains.leading to TLR3 lysosomal trafficking and degradation. Ubiquitinated by RNF170 at Lys-765 via 'Lys-48'-linked ubiquitin chains.leading to TLR3 proteasomal degradation.
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 the adapter TRIF/TICAM1, leading to NF-kappa-B activation, IRF3 nuclear translocation, cytokine secretion and the inflammatory response.
