Function
Constitutes a host TLR2 agonist (toll-like receptor), shown experimentally for human and mouse (PubMed:19362712). In host cells full-length (acylated) protein acts as a TLR2 agonist, inducing human and murine macrophages to produce cytokines, inducing murine dendritic cell maturation and cytokine production and inhibiting antibody processing in murine macrophages (PubMed:16785538). Binds diacylated phosphatidyl-myo-inositol mannosides (PIMs) (PubMed:20694006). Does not induce murine macrophage apoptosis or necrosis (PubMed:16785538). Non-acylated protein does not act as a TLR2 agonist (PubMed:20694006). Requires only host TLR2 as receptors to elicit host response in mouse, although TLR6 may play a redundant role, also requires CD14 and CD16 as accessory receptors (PubMed:19362712). {ECO:0000269|PubMed:16785538, ECO:0000269|PubMed:19362712, ECO:0000269|PubMed:20694006}.
