TLR3 Protein, Mouse (sf9, His)

TLR3 protein is an important component of innate and adaptive immunity and can recognize pathogen-associated molecular patterns and activate NF-κ-B, IRF3 and cytokine secretion. Ligand binding induces TLR3 dimerization, and efficient signal transduction requires clustering of signaling units along the ligand. TLR3 Protein, Mouse (sf9, His) is the recombinant mouse-derived TLR3 protein, expressed by Sf9 insect cells , with N-His labeled tag. The total length of TLR3 Protein, Mouse (sf9, His) is 677 a.a., with molecular weight of 75-80 kDa.

TLR3 protein serves as a key component in both innate and adaptive immunity, playing a pivotal role in the host immune response against pathogens by recognizing specific molecular patterns associated with microorganisms. Activated by double-stranded RNA, a characteristic feature of viral infection, TLR3 functions through the adapter TRIF/TICAM1, leading to NF-kappa-B activation, nuclear translocation of IRF3, cytokine secretion, and initiation of the inflammatory response. TLR3 exists as a monomer and homodimer, with ligand-binding triggering dimerization. The signaling unit comprises one approximately 40 bp ds-RNA and two TLR3 molecules, requiring lateral clustering of signaling units along the ds-RNA ligand for effective signal transduction. Interaction with UNC93B1, SRC, and TICAM1, particularly in response to poly(I:C), contributes to its regulatory functions, highlighting the intricate molecular mechanisms involved in TLR3-mediated immune responses.
