STRINGSTRING
STRING protein interaction network
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

PE13PE family protein PE13; May play a pivotal role in the interaction between M.tuberculosis and host. Can enhance the survival within macrophages under stress conditions such as H(2)O(2), SDS and low pH. Increases the production of IL-6 and IL-1beta from macrophages, and decreases the secretion of suppressor of cytokine signaling 3 (SOCS-3). These changes probably involve the p38-ERK-NF-kappa-B signaling pathway. Also precipitates the macrophage death. (99 aa)    
Predicted Functional Partners:
PPE18
PPE family protein PPE18; Could be a crucial virulence factor for intracellular survival of M.tuberculosis. Favors development of Th2-type response, and downregulates the proinflammatory and Th1-type response. Specifically interacts with the human Toll-like receptor 2 (TLR2), leading to an early and sustained activation of p38 MAPK, which induces IL-10 production and activates Th2-type immune response. Also inhibits proinflammatory cytokines IL-12p40 and TNF-alpha production. Acts by upregulating the expression as well as tyrosine phosphorylation of suppressor of cytokine signaling 3 ( [...]

esxL
Putative ESAT-6 like protein EsxL (ESAT-6 like protein 4); Induces apoptosis of host cells. Is immunogenic with highly specific seroreactivity towards TB patients' serum ; Belongs to the WXG100 family. ESAT-6 subfamily.

esxK
Rv1197, (MT1235, MTCI364.09), len: 98 aa. EsxK,ESAT-6 like protein (see citation below). Member of M. tuberculosis hypothetical QILSS protein family with Rv1038c, etc. Almost identical to MTCY98.023c (98 aa) (99.0% identity in 98 aa overlap) and MTCY10G2.11 (98 aa),FASTA scores: opt: 643, E(): 0, (99.0% identity in 98 aa overlap); highly similar to Q49945|U1756C from Mycobacterium leprae (100 aa), FASTA scores: opt: 377, E(): 8e-21, (58.3% identity in 96 aa overlap). Belongs to the ESAT6 family.

PE_PGRS11
PE-PGRS family protein PE_PGRS11; Induces maturation and activation of human dendritic cells (DCs), via TLR2-dependent activation of ERK1/2, p38 MAPK, and NF-kappa- B signaling pathways, and enhances the ability of DCs to stimulate CD4(+) T cells. By activating DCs, could potentially contribute to the initiation of innate immune responses during tuberculosis infection and hence regulate the clinical course of tuberculosis. Involved in resistance to oxidative stress, via TLR2-dependent activation of the PI3K-ERK1/2-NF-kappa-B signaling pathway and expression of COX-2 and Bcl2. Also abol [...]
