Biological function summary
TLR3 acts as a sensor for viral and endogenous dsRNA. This receptor forms part of the innate immune system serving as a first line of defense against microbial infections. Upon encountering its ligand TLR3 undergoes conformational changes which allow interaction with the adaptor protein TRIF (TIR-domain-containing adapter-inducing interferon-β). This interaction triggers a downstream signaling cascade that leads to the production of type I interferons and pro-inflammatory cytokines which are essential for mounting an effective antiviral response.
Pathways
TLR3 engages in important signaling cascades like the NF-kB and IRF3 pathways. These pathways are activated by the TRIF-dependent pathway which is unique among the Toll-like receptors. TLR3 influences the expression of genes involved in the inflammatory response and apoptosis. The interactions of TLR3 with other proteins such as MyD88 and IRAK1 are indirect as TLR3 does not depend on the usual MyD88-dependent pathway. This specificity makes TLR3 a critical component in pathogen recognition and response strategies within the immune system.

General info
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.
Sequence similarities
Belongs to the Toll-like receptor family.
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 (PubMed:32878999). Ubiquitinated by ZNRF1 via 'Lys-63'-linked ubiquitin chains; leading to TLR3 lysosomal trafficking and degradation (PubMed:37158982). Ubiquitinated by RNF170 at Lys-765 via 'Lys-48'-linked ubiquitin chains; leading to TLR3 proteasomal degradation (PubMed:31076723).
