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

raaSProbable transcriptional regulatory protein; Regulates the expression of the Rv1217c-Rv1218c multidrug efflux system and its own expression. Acts by binding to promoter regions of Rv1219c and upstream of the Rv1218c gene. Important for survival in prolonged stationary phase and during macrophage infection. May be used to eliminate non- growing mycobacteria. (212 aa)    
Predicted Functional Partners:
Rv1217c
Probable tetronasin-transport integral membrane protein ABC transporter; Probably part of the ABC transporter complex Rv1217c-Rv1218c involved in the resistance to a wide range of structurally unrelated drugs. Probably responsible for the translocation of the substrate across the membrane (Probable).
 
  
 0.983
Rv1218c
Probable tetronasin-transport ATP-binding protein ABC transporter; Probably part of the ABC transporter complex Rv1217c-Rv1218c involved in the resistance to a wide range of structurally unrelated drugs. Could be involved in the efflux of substrates belonging to the diverse chemical classes of novobiocins, biarylpiperazines, pyridines, bisanilinopyrimidines, pyrroles and, to a smaller extent, pyrazolones. Probably responsible for energy coupling to the transport system (Probable).
