STRINGSTRING
GPX1 protein (Saccharomyces cerevisiae) - STRING interaction network
"GPX1" - Phospholipid hydroperoxide glutathione peroxidase induced by glucose starvation that protects cells from phospholipid hydroperoxides and nonphospholipid peroxides during oxidative stress in Saccharomyces cerevisiae
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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

GPX1Phospholipid hydroperoxide glutathione peroxidase induced by glucose starvation that protects cells from phospholipid hydroperoxides and nonphospholipid peroxides during oxidative stress; May constitute a glutathione peroxidase-like protective system against oxidative stresses (167 aa)    
Predicted Functional Partners:
GLR1
Cytosolic and mitochondrial glutathione oxidoreductase, converts oxidized glutathione to reduced glutathione; mitochondrial but not cytosolic form has a role in resistance to hyperoxia; Maintains high levels of reduced glutathione in the cytosol (483 aa)
   
 
  0.997
GSH2
Glutathione synthetase, catalyzes the ATP-dependent synthesis of glutathione (GSH) from gamma-glutamylcysteine and glycine; induced by oxidative stress and heat shock (491 aa)
         
  0.972
URE2
Nitrogen catabolite repression transcriptional regulator that acts by inhibition of GLN3 transcription in good nitrogen source; has glutathione peroxidase activity and can mutate to acquire GST activity; altered form creates [URE3] prion; Plays an important role in nitrogen catabolite repression. Down-regulates the expression of many genes involved in nitrogen utilization by inhibiting the GATA transcriptional activators GLN3 and GAT1. Under good nitrogen conditions, binds to the phosphorylated forms of GLN3 and GAT1 and sequesters them in the cytoplasm, preventing transcription of gen [...] (354 aa)
     
 
  0.971
PDI1
Protein disulfide isomerase; multifunctional protein resident in the endoplasmic reticulum lumen, essential for the formation of disulfide bonds in secretory and cell-surface proteins, unscrambles non-native disulfide bonds; forms a complex with Mnl /.../t has exomannosidase activity, processing unfolded protein-bound Man8GlcNAc2 oligosaccharides to Man7GlcNAc2 which promotes degradation in the unfolded protein response; Protein disulfide isomerase of ER lumen required for formation of disulfide bonds in secretory and cell-surface proteins and which unscrambles non-native disulfide bon [...] (522 aa)
   
  0.970
EUG1
Protein disulfide isomerase of the endoplasmic reticulum lumen, function overlaps with that of Pdi1p; may interact with nascent polypeptides in the ER; Probably interacts with nascent polypeptides in the endoplasmic reticulum. It is an essential gene only in the absence of PDI. Its native disulfide isomerase activity is very low (517 aa)
   
  0.960
SOD2
Mitochondrial manganese superoxide dismutase; protects cells against oxygen toxicity; Destroys superoxide anion radicals which are normally produced within the cells and which are toxic to biological systems (233 aa)
     
  0.948
ECM38
Gamma-glutamyltranspeptidase, major glutathione-degrading enzyme; involved in detoxification of electrophilic xenobiotics; expression induced mainly by nitrogen starvation; Catalyzes the transfer of the gamma-glutamyl moiety of glutathione (GSH) and other gamma-glutamyl compounds to amino acids and peptides. Major GSH-degrading enzyme, catalyzing the hydrolytic release of L-glutamate from GSH. Plays a role in the turnover of the vacuolar GSH, serving as an alternative nitrogen source during nitrogen starvation (660 aa)
     
 
  0.944
GTT1
ER associated glutathione S-transferase capable of homodimerization; expression induced during the diauxic shift and throughout stationary phase; functional overlap with Gtt2p, Grx1p, and Grx2p (234 aa)
     
 
  0.944
SOD1
Cytosolic copper-zinc superoxide dismutase; some mutations are analogous to those that cause ALS (amyotrophic lateral sclerosis) in humans; Destroys radicals which are normally produced within the cells and which are toxic to biological systems (154 aa)
     
  0.939
ERO1
Thiol oxidase required for oxidative protein folding in the endoplasmic reticulum; Essential oxidoreductase that oxidizes proteins in the endoplasmic reticulum to produce disulfide bonds. Acts by oxidizing directly PDI1 isomerase through a direct disulfide exchange. Does not act as a direct oxidant of folding substrate, but relies on PDI1 to transfer oxidizing equivalent. Also able to oxidize directly the PDI related protein MPD2. Does not oxidize all PDI related proteins, suggesting that it can discriminate between PDI1 and related proteins. Reoxidation of ERO1 probably involves elect [...] (563 aa)
