DESCRIPTION

Also known as TLR1_HUMAN, TLR1, KIAA0012. Participates in the innate immune response to microbial agents. Specifically recognizes diacylated and triacylated lipopeptides. Cooperates with TLR2 to mediate the innate immune response to bacterial lipoproteins or lipopeptides (PubMed:21078852). Forms the activation cluster TLR2:TLR1:CD14 in response to triacylated lipopeptides, this cluster triggers signaling from the cell surface and subsequently is targeted to the Golgi in a lipid-raft dependent pathway (PubMed:16880211). Acts via MYD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. Interacts (via extracellular domain) with TLR2. 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, PubMed:17889651). The activation cluster TLR2:TLR1:CD14 forms in response to triacylated lipopeptides (PubMed:16880211). Binds MYD88 (via TIR domain). Interacts with CNPY3 (By similarity).
