ESAT-6 like protein EsxG (conserved protein TB9.8); EsxG, in complex with EsxH, disrupts ESCRT function and impairs host phagosome maturation, thereby promoting intracellular bacterial growth. The complex acts by interacting, via EsxH, with the host hepatocyte growth factor-regulated tyrosine kinase substrate (HGS/HRS), a component of the ESCRT machinery. EsxG stabilizes EsxH in the host cytosol.

6 kDa early secretory antigenic target EsxA (ESAT-6); A secreted protein that plays a number of roles in modulating the host's immune response to infection as well as being responsible for bacterial escape into the host cytoplasm. Acts as a strong host (human) T-cell antigen. Inhibits IL- 12 p40 (IL12B) and TNF-alpha expression by infected host (mouse) macrophages, reduces the nitric oxide response by about 75%. In mice previously exposed to the bacterium, elicits high level of IFN-gamma production by T-cells upon subsequent challenge by M.tuberculosis, in the first phase of a protecti [...]

Rv3018A, len: 28 aa. PE27A, Member of Mycobacterium tuberculosis PE family (see Brennan and Delogu, 2002), most similar to Rv0285 (102 aa), FASTA scores: opt: 147, E(): 3.5e-05, (92.85% identity in 28 aa overlap); etc.

Rv3018c, (MTV012.32c), len: 434 aa. PPE46, Member of PPE family but lacks Gly, Ala rich repeats at C-terminal domain, closest to MTCY261.19. See citation below. Also very similar to following ORF MTV012.35c. Nearly identical in parts to Mycobacterium tuberculosis protein erroneously described as dihydrofolate reductase (X59271|MTFOLA_1) P31500|DYR_MYCTU (214 aa), FASTA scores: opt: 972, E(): 4.4e-42, (80.0% identity in 195 aa overlap); and Z97559|MTCY261_19 from Mycobacterium tuberculosis cosmid (473 aa), FASTA scores: opt: 806, E(): 0; (38.8% identity in 479 aa overlap); and O53268|MT [...]

10 kDa culture filtrate antigen EsxB (LHP) (CFP10); A secreted protein. Acts as a strong host (human) T-cell antigen. Involved in translocation of bacteria from the host (human) phagolysosome to the host cytoplasm. Might serve as a chaperone to prevent uncontrolled membrane lysis by its partner EsxA; native protein binds poorly to artificial liposomes in the absence or presence of EsxA. EsxA and EsxA-EsxB are cytotoxic to pneumocytes. EsxB (and EsxA-EsxB but not EsxA alone) activates human neutrophils; EsxB transiently induces host (human) intracellular Ca(2+) mobility in a dose-depend [...]

Conserved protein; Rv1769, (MTCY28.35), len: 414 aa. Conserved protein,similar to O88066|SCI35.31|AL031541 hypothetical protein from Streptomyces coelicolor (402 aa), FASTA scores: opt: 1341, E(): 0, (53.8% identity in 398 aa overlap).
