[https://www.uniprot.org/uniprot/Q4G1L2_EPTBU Q4G1L2_EPTBU] [https://www.uniprot.org/uniprot/TLR9_MOUSE TLR9_MOUSE] 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. Plays a role in defense against systemic mouse cytomegalovirus infection. Controls lymphocyte response to Helicobacter infection.<ref>PMID:14993594</ref> <ref>PMID:17474149</ref> | |||

== Publication Abstract from PubMed == | |||
Toll-like receptors (TLRs) are important pattern recognition receptors that function in innate immunity. Elucidating the structure and signaling mechanisms of TLR9, a sensor of foreign and endogenous DNA, is essential for understanding its key role in immunity against microbial pathogens as well as in autoimmunity. Abundant evidence suggests that the TLR9-CTD (C-terminal domain) by itself is capable of DNA binding and signaling. The crystal structure of unliganded mouse TLR9-CTD is presented. TLR9-CTD exhibits one unique feature, a cluster of stacked aromatic and arginine side chains on its concave face. Overall, its structure is most related to the TLR8-CTD, suggesting a similar mode of ligand binding and signaling. Proteins 2014;. (c) 2014 Wiley Periodicals, Inc. | |||
