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:
some 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

OPT1Proton-coupled oligopeptide transporter of the plasma membrane; also transports glutathione and phytochelatin; member of the OPT family (799 aa)    
Predicted Functional Partners:
PTR2
Proton-dependent oligopeptide transporter, pot family; Integral membrane peptide transporter; mediates transport of di- and tri-peptides; conserved protein that contains 12 transmembrane domains; PTR2 expression is regulated by the N-end rule pathway via repression by Cup9p
   
 
 0.948
YGL114W
Putative oligopeptide transporter ygl114w; Putative protein of unknown function; predicted member of the oligopeptide transporter (OPT) family of membrane transporters
   
  
 0.903
GSH1
Glutamate--cysteine ligase; Gamma glutamylcysteine synthetase; catalyzes the first step in glutathione (GSH) biosynthesis; expression induced by oxidants, cadmium, and mercury; protein abundance increases in response to DNA replication stress; Belongs to the glutamate--cysteine ligase type 3 family
    
 
 0.823
GSH2
Glutathione synthetase; catalyzes the ATP-dependent synthesis of glutathione (GSH) from gamma-glutamylcysteine and glycine; induced by oxidative stress and heat shock
    
 
 0.788
ECM38
Glutathione hydrolase proenzyme; Gamma-glutamyltranspeptidase; major glutathione-degrading enzyme; involved in detoxification of electrophilic xenobiotics; expression induced mainly by nitrogen starvation; Belongs to the gamma-glutamyltransferase family
      
 0.770
MET17
Bifunctional cysteine synthase/o-acetylhomoserine aminocarboxypropyltransferase met17; Homocysteine/cysteine synthase; O-acetyl homoserine-O-acetyl serine sulfhydrylase; required for Methionine and cysteine biosynthesis; Belongs to the trans-sulfuration enzymes family
    
 
 0.689
GAP1

 0.653
DUG1
Cys-Gly metallodipeptidase DUG1; Cys-Gly metallo-di-peptidase; forms a complex with Dug2p and Dug3p to degrade glutathione (GSH) and other peptides containing a gamma-glu-X bond in an alternative pathway to GSH degradation by gamma-glutamyl transpeptidase (Ecm38p); human homolog CNDP2 can complement yeast dug1 mutant
   
 
 0.648
DUG3
Probable glutamine amidotransferase dug3; Component of glutamine amidotransferase (GATase II); forms a complex with Dug2p to degrade glutathione (GSH) and other peptides containing a gamma-glu-X bond in an alternative pathway to GSH degradation by gamma-glutamyl transpeptidase (Ecm38p)
   
  
 0.633
MET10
