  • Function
    Key component of innate and adaptive immunity. TLRs (Toll-like receptors) control host immune response against pathogens through recognition of molecular patterns specific of microorganisms. TLR9 is a nucleotide-sensing TLR which is activated by unmethylated cytidine-phosphate-guanosine (CpG) dinucleotides. Acts via MYD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response.
  • Tissue specificity
    Highly expressed in spleen, lymph node, tonsil and peripheral blood leukocytes, especially in plasmacytoid pre-dendritic cells. Levels are much lower in monocytes and CD11c+ immature dendritic cells. Also detected in lung and liver.
  • Sequence similarities
    Belongs to the Toll-like receptor family.
    Contains 26 LRR (leucine-rich) repeats.
    Contains 1 TIR domain.
  • Cellular localization
    Endoplasmic reticulum membrane. Endosome. Lysosome. Cytoplasmic vesicle > phagosome. Relocalizes from endoplasmic reticulum to endosome and lysosome upon stimulation with agonist.

Thank you for contacting us.

My colleague got back to me and we have now re-published ab52967.
Could you please just quickly confirm that I will send you 1 vial of ab52967 free of charge to replace ab134368?
The estimated delivery date will be in about 1-2 weeks, but I will have a more concrete date, once I create the free of charge order and will let you know it.

I look forward to hear back from you hope and resolve this case.

Thank you for your patience. I have enquired at the originator of the product but unfortunately, the amino acid sequence is proprietary information and cannot be disclosed. I am sorry I can't be of more assistance in this occasion but should you require any other information, please do not hesitate to contact me.
