Protein
PE-PGRS family protein PE_PGRS33
Organism
Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Function
Induces TNF-alpha release through human Toll-like receptor 2 (TLR2) signaling pathway, leading to macrophage apoptosis (PubMed:17095513, PubMed:17223373, PubMed:24106104). The signaling pathway involves TLR2-dependent activation of the mitogen-activated protein kinase kinase kinase 5 (ASK1), which activates the p38 and JNK MAPKs, leading to enhanced expression of TNF-alpha and tumor necrosis factor receptor superfamily member 1A (TNFRI) genes. Signals are amplified through classical caspase 8-dependent mitochondrial release of cytochrome c, leading to the activation of caspases 9 and 3 (PubMed:17095513). Mediates Ca(2+)-dependent up-regulation of the anti-inflammatory cytokine IL-10 (PubMed:27483162). Mediates entry into macrophages in a TLR2-dependent mechanism and activates the TLR2-dependent pro-adhesive pathway (PubMed:26978522).
Similarity
Belongs to the mycobacterial PE family. PGRS subfamily.
