DESCRIPTION

Also known as IPYR_MYCTU, ppa. Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions., Antigen that activates dendritic cells (DCs), increasing their expression of cell surface molecules and augmenting their production of TNF-alpha, IL-1beta, IL-6, IL-23 and IL-12p70. Rv3628 mediates these effects by binding to TLR2 and activating downstream MyD88-, MAPK- and NF-kappaB-dependent signaling pathways. Rv3628-stimulated DCs induce the expansion of OVA-specific CD4+ and CD8+ T cells which secrete IFN-gamma and IL-2, and the generation of effector/memory T cells. Thus, Rv3628 polarizes DCs toward a Th1 immune response and promotes protective immunity against M.tuberculosis infection. Is not able to bind to TLR4 molecules on the cell surface. Homohexamer.
