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

PE_PGRS5PE-PGRS family protein PE_PGRS5; Involved in endoplasmic reticulum (ER) stress-mediated apoptosis through human Toll-like receptor 4 (TLR4) signaling pathway. Localizes to the host ER, leading to ER stress, disruption of intracellular Ca(2+) homeostasis and increase of nitric oxide (NO) and reactive oxygen species (ROS) levels. Stress response results in caspase-8 activation and apoptosis of macrophage cells. Apoptosis may lead to dissemination of the bacteria, thereby spreading the disease. Belongs to the mycobacterial PE family. PGRS subfamily. (591 aa)

stf0
Conserved protein; Catalyzes the sulfuryl group transfer from 3'- phosphoadenosine-5'-phosphosulfate (PAPS) to trehalose, leading to trehalose-2-sulfate (T2S). The sulfation of trehalose is the first step in the biosynthesis of sulfolipid-1 (SL-1), a major cell wall glycolipid and the most abundant sulfated metabolite found in Mycobacterium tuberculosis, that is a potential virulence factor thought to mediate host-pathogen interactions.
