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.SUBUNIT Monomer and homodimer; dimerization is triggered by ligand-binding, the signaling unit is composed of one ds-RNA of around 40 bp and two TLR3 molecules, and lateral clustering of signaling units along the length of the ds-RNA ligand is required for TLR3 signal transduction. Interacts (via transmembrane domain) with UNC93B1; the interaction is required for transport from the ER to the endosomes (PubMed:33432245). Interacts with SRC; upon binding of double-stranded RNA. Interacts with TICAM1 (via the TIR domain) in response to poly(I:C) and this interaction is enhanced in the presence of WDFY1 (PubMed:25736436). The tyrosine-phosphorylated form (via TIR domain) interacts with WDFY1 (via WD repeat 2) in response to poly(I:C) (PubMed:25736436).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.PTM Heavily N-glycosylated, except on that part of the surface of the ectodomain that is involved in ligand binding.PTM 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.POLYMORPHISM The Phe-412 allele (dbSNP:rs3775291) occurs with a frequency of 30% in populations with European and Asian ancestry, and confers some natural resistance to HIV-1 infection.SIMILARITY Belongs to the Toll-like receptor family.

Plays an important role in the cascades of cellular responses evoked by changes in the environment. Mediates signal transduction of TRAF6, various cytokines including interleukin-1 (IL-1), transforming growth factor-beta (TGFB), TGFB-related factors like BMP2 and BMP4, toll-like receptors (TLR), tumor necrosis factor receptor CD40 and B-cell receptor (BCR). Ceramides are also able to activate MAP3K7/TAK1. Once activated, acts as an upstream activator of the MKK/JNK signal transduction cascade and the p38 MAPK signal transduction cascade through the phosphorylation and activation of several MAP kinase kinases like MAP2K1/MEK1, MAP2K3/MKK3, MAP2K6/MKK6 and MAP2K7/MKK7. These MAP2Ks in turn activate p38 MAPKs, c-jun N-terminal kinases (JNKs) and I-kappa-B kinase complex (IKK). Both p38 MAPK and JNK pathways control the transcription factors activator protein-1 (AP-1), while nuclear factor-kappa B is activated by IKK. MAP3K7 activates also IKBKB and MAPK8/JNK1 in response to TRAF6 signaling and mediates BMP2-induced apoptosis. In osmotic stress signaling, plays a major role in the activation of MAPK8/JNK1, but not that of NF-kappa-B. Promotes TRIM5 capsid-specific restriction activity. Phosphorylates RIPK1 at 'Ser-321' which positively regulates RIPK1 interaction with RIPK3 to promote necroptosis but negatively regulates RIPK1 kinase activity and its interaction with FADD to mediate apoptosis (By similarity).ACTIVITY REGULATION Activated by pro-inflammatory cytokines and in response to physical and chemical stresses, including osmotic stress, oxidative stress, arsenic and ultraviolet light irradiation. Activated by 'Lys-63'-linked polyubiquitination and by autophosphorylation. Association with TAB1/MAP3K7IP1 and TAB2/MAP3K7IP2 promotes activation through autophosphorylation, whereas PPM1B/PP2CB, PP2A and PPP6C dephosphorylation leads to inactivation.SUBUNIT Can form homodimer (PubMed:27426733). Binds both upstream activators and downstream substrates in multimolecular complexes. Interacts with TAB1/MAP3K7IP1, TAB2/MAP3K7IP2 and TAB3/MAP3K7IP3 (PubMed:10838074, PubMed:11460167, PubMed:12242293, PubMed:14670075, PubMed:16289117, PubMed:19675569, PubMed:8638164). Identified in the TRIKA2 complex composed of MAP3K7/TAK1, TAB1/MAP3K7IP1 and TAB2/MAP3K7IP2 (PubMed:11460167). Interacts with PPM1L and PPM1B/PP2CB (PubMed:11104763). Interaction with PP2A and PPP6C leads to its repressed activity (PubMed:17079228). Interacts with TRAF6 and TAB1/MAP3K7IP1; during IL-1 signaling (PubMed:10094049, PubMed:12242293). Interacts with TAOK1 and TAOK2; interaction with TAOK2 interferes with MAP3K7 interaction with IKKA, thus preventing NF-kappa-B activation (PubMed:16893890). Interacts with DYNC2I2 (via WD domains) (PubMed:19521662). Interacts with CYLD and RBCK1 (PubMed:17449468, PubMed:17548520). Interacts with TGFBR1; induces MAP3K7/TAK1 activation by TRAF6 (PubMed:18758450). Interacts with MAPK8IP1 and SMAD6 (By similarity). Interacts with isoform 1 of VRK2 (PubMed:18286207). Interacts with DAB2; the interaction is induced by TGF-beta stimulation and may mediate TGF-beta stimulated JNK activation (PubMed:15894542). Interacts with TRIM5 (PubMed:21512573). Part of a complex containing ITCH, NDFIP1 and MAP3K7 (By similarity). Interacts with IFIT5; the interaction synergizes the recruitment of IKK to MAP3K7 and enhances IKK phosphorylation (PubMed:26334375). Interacts with PLEKHM1 (via N- and C-terminus) (By similarity). Interacts with TRIM8 (PubMed:22084099). Found in a complex with SH3RF1, RAC2, MAP2K7/MKK7, MAPK8IP1/JIP1, MAPK8/JNK1 and MAPK9/JNK2 (By similarity). Interacts with SASH1 (PubMed:23776175). Interacts with RIPK1 (By similarity).SUBUNIT (Microbial infection) Interacts with herpes simplex virus 2 protein US2; this interaction induces MAP3K7 phosphorylation and subsequent activation.TISSUE SPECIFICITY Isoform 1A is the most abundant in ovary, skeletal muscle, spleen and blood mononuclear cells. Isoform 1B is highly expressed in brain, kidney and small intestine. Isoform 1C is the major form in prostate. Isoform 1D is the less abundant form.PTM Association with TAB1/MAP3K7IP1 promotes autophosphorylation at Ser-192 and subsequent activation. Association with TAB2/MAP3K7IP2, itself associated with free unanchored Lys-63 polyubiquitin chain, promotes autophosphorylation and subsequent activation of MAP3K7. Dephosphorylation at Ser-192 by PPM1B/PP2CB and at Thr-187 by PP2A and PPP6C leads to inactivation.PTM 'Lys-48'-linked polyubiquitination at Lys-72 is induced by TNFalpha, and leads to proteasomal degradation. Undergoes 'Lys-48'-linked polyubiquitination catalyzed by ITCH (By similarity). Requires 'Lys-63'-linked polyubiquitination for autophosphorylation and subsequent activation. 'Lys-63'-linked ubiquitination does not lead to proteasomal degradation. Deubiquitinated by CYLD, a protease that selectively cleaves 'Lys-63'-linked ubiquitin chains. Deubiquitinated by Y.enterocolitica YopP.PTM (Microbial infection) Cleaved and inactivated by the proteases 3C of coxsackievirus A16 and human enterovirus D68, allowing the virus to disrupt TRAF6-triggered NF-kappa-B induction.PTM (Microbial infection) Acetylation of Thr-184 and Thr-187 by Yersinia YopJ prevents phosphorylation and activation, thus blocking the MAPK signaling pathway.SIMILARITY Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase kinase subfamily.
