Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

esxGESAT-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. (97 aa)
espJESX-1 secretion-associated protein EspJ. Conserved alanine rich protein; Could be involved in regulation of growth and intracellular survival. (280 aa)
esxB10 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 [...] (100 aa)

Stimulates high levels of gamma interferon secretion in peripheral blood mononuclear cells isolated from tuberculosis patients, as well as from healthy tuberculin purified protein derivative-positive donors. Does not interfere with the secretion and immunogenicity of EsxA (ESAT-6) [...] (368 aa)
