Function
function
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. 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. Upon CpG stimulation, induces B-cell proliferation, activation, survival and antibody production.

Interaction
Subunit
Monomer and homodimer. Exists as a monomer in the absence of unmethylated cytidine-phosphate-guanosine (CpG) ligand. Proteolytic processing of an insertion loop (Z-loop) is required for homodimerization upon binding to the unmethylated CpG ligand leading to its activation. Interacts with MYD88 via their respective TIR domains. Interacts with BTK. Interacts (via transmembrane domain) with UNC93B1. Interacts with CD300LH; the interaction may promote full activation of TLR9-triggered innate responses. Interacts with CNPY3 and HSP90B1; this interaction is required for proper folding in the endoplasmic reticulum. Interacts with SMPDL3B. Interacts with CD82; this interaction is essential for TLR9-dependent myddosome formation in response to CpG stimulation.
