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 (PubMed:21078852, PubMed:17889651). Acts via MYD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. May also activate immune cells and promote apoptosis in response to the lipid moiety of lipoproteins (PubMed:10426995, PubMed:10426996). 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 (PubMed:11441107). Stimulation of monocytes in vitro with M.tuberculosis PstS1 induces p38 MAPK and ERK1/2 activation primarily via this receptor, but also partially via TLR4 (PubMed:16622205). MAPK activation in response to bacterial peptidoglycan also occurs via this receptor (PubMed:16622205). Acts as a receptor for M.tuberculosis lipoproteins LprA, LprG, LpqH and PstS1, some lipoproteins are dependent on other coreceptors (TLR1, CD14 and/or CD36); the lipoproteins act as agonists to modulate antigen presenting cell functions in response to the pathogen (PubMed:19362712). M.tuberculosis HSP70 (dnaK) but not HSP65 (groEL-2) acts via this protein to stimulate NF-kappa-B expression (PubMed:15809303). Recognizes M.tuberculosis major T-antigen EsxA (ESAT-6) which inhibits downstream MYD88-dependent signaling (shown in mouse) (By similarity). Forms activation clusters composed of several receptors depending on the ligand, these clusters trigger signaling from the cell surface and subsequently are targeted to the Golgi in a lipid-raft dependent pathway. Forms the cluster TLR2:TLR6:CD14:CD36 in response to diacylated lipopeptides and TLR2:TLR1:CD14 in response to triacylated lipopeptides (PubMed:16880211). Required for normal uptake of M.tuberculosis, a process that is inhibited by M.tuberculosis LppM (By similarity).By similarity9 Publications

Interacts with LY96, TLR1 and TLR6 (via extracellular domain) (PubMed:17889651). TLR2 seems to exist in heterodimers with either TLR1 or TLR6 before stimulation by the ligand. The heterodimers form bigger oligomers in response to their corresponding ligands as well as further heterotypic associations with other receptors such as CD14 and/or CD36 (PubMed:16880211). Binds MYD88 (via TIR domain).

Genetic variations in TLR2 are associated with susceptibility to leprosy [MIMi:246300]. Leprosy is a chronic disease associated with depressed cellular (but not humoral) immunity, the bacterium requires a lower temperature than 37 degrees Celsius and thrives particularly in peripheral Schwann cells and macrophages. The Trp-677 polymorphism in the intracellular domain of TLR2 has a role in susceptibility to lepromatous leprosy. Wild-type TLR2 mediates CD14-enhanced Mycobacterium leprae-dependent activation of NFKB1, but TLR2 containing the Trp-677 polymorphism did not. The impaired function of the Trp-677 polymorphism provides a molecular mechanism for the poor cellular immune response associated with lepromatous leprosy.2 Publications
