CC -!- FUNCTION: Induces TNF-alpha release through human Toll-like receptor 2
CC (TLR2) signaling pathway, leading to macrophage apoptosis
CC (PubMed:17095513, PubMed:17223373, PubMed:24106104). The signaling
CC pathway involves TLR2-dependent activation of the mitogen-activated
CC protein kinase kinase kinase 5 (ASK1), which activates the p38 and JNK
CC MAPKs, leading to enhanced expression of TNF-alpha and tumor necrosis
CC factor receptor superfamily member 1A (TNFRI) genes. Signals are
CC amplified through classical caspase 8-dependent mitochondrial release
CC of cytochrome c, leading to the activation of caspases 9 and 3
CC (PubMed:17095513). Mediates Ca(2+)-dependent up-regulation of the anti-
CC inflammatory cytokine IL-10 (PubMed:27483162). Mediates entry into
CC macrophages in a TLR2-dependent mechanism and activates the TLR2-
CC dependent pro-adhesive pathway (PubMed:26978522).
CC {ECO:0000269|PubMed:17095513, ECO:0000269|PubMed:17223373,
CC ECO:0000269|PubMed:24106104, ECO:0000269|PubMed:26978522,
CC ECO:0000269|PubMed:27483162}.
CC -!- ACTIVITY REGULATION: Binding of Ca(2+) to PE_PGRS33 induces
CC conformational changes and increases affinity for TLR2.
CC {ECO:0000269|PubMed:27483162}.
CC -!- SUBUNIT: Interacts with human TLR2. {ECO:0000269|PubMed:17095513,
CC ECO:0000269|PubMed:26978522, ECO:0000269|PubMed:27483162}.
CC -!- SUBCELLULAR LOCATION: Secreted, cell wall {ECO:0000269|PubMed:15101979,
CC ECO:0000269|PubMed:18028308, ECO:0000269|PubMed:22110736,
CC ECO:0000269|PubMed:27483162}. Cell surface
CC {ECO:0000269|PubMed:15101979, ECO:0000269|PubMed:18028308,
CC ECO:0000269|PubMed:18957600, ECO:0000269|PubMed:22110736,
CC ECO:0000269|PubMed:27483162}. Cell outer membrane
CC {ECO:0000269|PubMed:18028308}. Note=Exported to the cell surface via
CC the ESX-5 / type VII secretion system (T7SS) (PubMed:22110736).
CC Localizes mostly at the cell poles (PubMed:15101979). Colocalizes to
CC mitochondria in transfected eukaryotic cells (PubMed:17223373,
CC PubMed:21081760). {ECO:0000269|PubMed:15101979,
CC ECO:0000269|PubMed:17223373, ECO:0000269|PubMed:21081760,
CC ECO:0000269|PubMed:22110736}.
CC -!- INDUCTION: Constitutively expressed in vitro, suggesting that it could
CC be an essential gene (PubMed:11967065, PubMed:16672626). Expression is
CC regulated by SigA. Down-regulated during stationary phase, under
CC nutrient starvation and oxygen depletion (PubMed:19068228).
CC {ECO:0000269|PubMed:11967065, ECO:0000269|PubMed:16672626,
CC ECO:0000269|PubMed:19068228}.
CC -!- DOMAIN: Contains an N-terminal PE domain, followed by a conserved
CC linker region and a C-terminal PGRS domain (PubMed:18028308,
CC PubMed:21081760). The PE domain is responsible for the export and
CC localization to the cell wall (PubMed:15101979, PubMed:18028308,
CC PubMed:22110736). The PGRS domain is required for TNF-alpha secretion
CC and is responsible for the main immunomodulatory properties of the
CC protein (PubMed:17095513, PubMed:24106104). Variations within the PGRS
CC domain alter the levels of TNF-alpha induction and are likely to have
CC an impact on the innate immune response (PubMed:17095513). PGRS domain
CC is also required to mediate cell entry into macrophages
CC (PubMed:26978522). Colocalization to the mitochondria of host cells is
CC dependent on the linker region and the PGRS domain, but not the PE
CC domain (PubMed:21081760). {ECO:0000269|PubMed:15101979,
CC ECO:0000269|PubMed:17095513, ECO:0000269|PubMed:18028308,
CC ECO:0000269|PubMed:21081760, ECO:0000269|PubMed:22110736,
CC ECO:0000269|PubMed:24106104, ECO:0000269|PubMed:26978522}.
CC -!- DISRUPTION PHENOTYPE: Deletion mutant is strongly impaired in its
CC ability to enter macrophages. Deletion does not affect the
CC intracellular growth in macrophages. {ECO:0000269|PubMed:26978522}.
CC -!- BIOTECHNOLOGY: PE domain induces protective cellular immune response
CC and PGRS domain induces humoral immune response during infection in
CC mice, suggesting that this protein is a promising candidate for the
CC development of M.tuberculosis vaccines (PubMed:11500435). Immunization
CC of mice with the PE_PGRS33 protein stimulated CD4(+) and CD8(+) T-cell
CC proliferation as well as IFN-gamma secretion, supporting the potential
CC use of PE_PGRS33 as a vaccine candidate for tuberculosis
CC (PubMed:24904584). Elicits a strong B-cell humoral response among
CC different clinical categories of both adult and child tuberculosis
CC patients, indicating that it could be used in the serodiagnosis of
CC tuberculosis (PubMed:17687113). {ECO:0000269|PubMed:11500435,
CC ECO:0000269|PubMed:17687113, ECO:0000269|PubMed:24904584}.
CC -!- MISCELLANEOUS: Expression of this gene in M.smegmatis leads to low
CC levels of NO and IL-12, increased level of IL-10 and better survival of
CC recombinant strains in macrophages. {ECO:0000269|PubMed:18957600}.
CC -!- SIMILARITY: Belongs to the mycobacterial PE family. PGRS subfamily.
CC {ECO:0000305}.
