Immunogen Peptide containing H-539 and N-541 .Remarks: H-539 and N-541 are two important amino acids involved in the binding of dsRNA to TLR3. The amino acid sequence used as immunogen is 100% homologous in human, rhesus monkey, macaque, orangutan, gorilla, chimpanzee, cow, and opossum, 95% homologous in dog and wild boar, 90% homologous in cat and rat, and 85% homologous in mouse.
Specificity This antibody detects CD283 / TLR3 (ligand binding domain). Species Reactivity: Tested: Chimpanzee, Cow, Gorilla, Human, Macaque, Mouse, Opossum, Rat. Expected from sequence similarity: Cat, Dog.
Purification Antigen Affinity Chromatography
Alternative Name CD283 / TLR3 (TLR3 Antibody Abstract)
Background The Toll-like receptor (TLR) family in mammal comprises a family of transmembrane proteins characterized by multiple copies of leucine rich repeats in the extracellular domain and IL-1 receptor motif in the cytoplasmic domain. Like its counterparts in Drosophila, TLRs signal through adaptor molecules (1) and could constitute an important and unrecognized component of innate immunity in humans. The TLR family is a phylogenetically conserved mediator of innate immunity that is essential for microbial recognition (2). Ten human homologs of TLRs (TLR1-10) have been described (3). TLR3 has a restricted expression pattern being expressed in dendritic cells (DC) and lymph nodes (4,5). The expression of TLR3 in a single cell type may indicate a specific role for this molecule in a restricted setting. TLR3 is activated by dsRNA, the genetic material of some viruses, and a viral replication intermediate in others (6). Crystal struture and mutational analyses of TLR3-ectodomain suggest that Histidine-539 and Asparagine-541 are important amino acid residues in the recognition of dsRNA. H539E and N541A mutations abolish the dsRNA binding and ligand-dependent activation of TLR3 (7). This polyclonal antibody may block dsRNA binding to TLR3.
