General description
TLR-3 is a single-pass type I receptor that binds to and signals the presence of microbial pathogens and double stranded RNA (dsRNA) viruses. Signaling through TLR-3 can promote the NF-kB pathway to initiate innate and adaptive immune responses to bacterial and viral infections, as well as the p53 pathway to trigger apoptosis in cells infected with dsRNA viruses. TLR-3 belongs to a family of structurally-related toll-like receptors (TLRs) containing an N-terminal domain rich in leucine repeats and a C-terminal intracellular Toll/interleukin (IL)-1 (TIL) domain. TLR-3 is expressed primarily in dendritic cells of the placenta and pancreas where it can reside on both sides of the plasma membrane and in the endosomal compartment of the cells. Recombinant human TLR-3 is 77.0 kDa glycoprotein containing 681 residues which comprise the TLR-3 extracellular domain.

Physical form
Lyophilized from 20 mM Sodium Phosphate, pH 7.5.
Reconstitution
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.

Trends in immunology, 26(9), 462-468 (2005-07-20)
Toll-like receptor 3 (TLR3), which recognizes double-stranded (ds)RNA, was the first identified antiviral TLR and, because dsRNA is a universal viral molecular pattern, TLR3 has been assumed to have a central role in the host response to viruses. However, this
Manabu Taura et al.
Molecular and cellular biology, 28(21), 6557-6567 (2008-09-10)
Toll-like receptors (TLRs) are important sensors of microbial pathogens and mediators of innate immune responses. Although the signal transduction of TLRs is well elucidated, their basal regulation is largely unexplored. Here we show that the tumor suppressor p53 positively regulates
