Function

[TLR2_HUMAN] Cooperates with LY96 to mediate the innate immune response to bacterial lipoproteins and other microbial cell wall components. Cooperates with TLR1 or TLR6 to mediate the innate immune response to bacterial lipoproteins or lipopeptides. Acts via MYD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. May also promote apoptosis in response to lipoproteins. Recognizes mycoplasmal macrophage-activating lipopeptide-2kD (MALP-2), soluble tuberculosis factor (STF), phenol-soluble modulin (PSM) and B.burgdorferi outer surface protein A lipoprotein (OspA-L) cooperatively with TLR6.

Publication Abstract from PubMed

The Toll/interleukin-1 receptor (TIR) domains are conserved modules in the intracellular regions of the Toll-like receptors (TLRs) and interleukin-1 receptors (IL-1Rs). The domains are crucial for the signal transduction by these receptors, through homotypic interactions among the receptor and the downstream adapter TIR domains. Previous studies showed that the BB loop in the structure of the TIR domain forms a prominent conserved feature on the surface and is important for receptor signaling. Here we report the crystal structure of the C713S mutant of the TIR domain of human TLR2. An extensively associated dimer is observed in the crystal structure and mutations of several residues in this dimer interface abolished the function of the receptor. Moreover, the structure shows that the BB loop can adopt different conformations, which are required for the formation of this dimer. This asymmetric dimer might represent the TLR2:TLRx heterodimer in the function of this receptor.
