• Concentration: 1mg/ml (varies by lot)

• Applicable Applications for anti-TLR3 antibody: Western Blot (WB), Peptide ELISA (EIA)
• Application Notes: WB: 1:500-1:2000; Peptide ELISA: 1:20,000-1:40,000
• Immunogen: A synthesized peptide derived from human TLR3 around the phosphorylation site of Tyr858.
• Conjugation: Unconjugated
• Fragment: Fab fragment
• 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.
• Subunit Structure: 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. 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. The tyrosine-phosphorylated form (via TIR domain) interacts with WDFY1 (via WD repeat 2) in response to poly (I:C).
• Similarity: ds-RNA binding is mediated by LRR 1 to 3, and LRR 17 to 18.Belongs to the Toll-like receptor family.
• Subcellular Location: Endoplasmic reticulum membrane>Single-pass type I membrane protein. Endosome membrane. Early endosome.
• Preparation and Storage: Store at -20 degree C. Stable for 12 months from date of receipt.

Related Product Information for anti-TLR3 antibody

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.

NCBI Description

The protein encoded by this gene is a member of the Toll-like receptor (TLR) family which plays a fundamental role in pathogen recognition and activation of innate immunity. TLRs are highly conserved from Drosophila to humans and share structural and functional similarities. They recognize pathogen-associated molecular patterns (PAMPs) that are expressed on infectious agents, and mediate the production of cytokines necessary for the development of effective immunity. The various TLRs exhibit different patterns of expression. This receptor is most abundantly expressed in placenta and pancreas, and is restricted to the dendritic subpopulation of the leukocytes. It recognizes dsRNA associated with viral infection, and induces the activation of NF-kappaB and the production of type I interferons. It may thus play a role in host defense against viruses. Use of alternative polyadenylation sites to generate different length transcripts has been noted for this gene. [provided by RefSeq, Jul 2008]
