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

GPX4Phospholipid hydroperoxide glutathione peroxidase; Essential antioxidant peroxidase that directly reduces phospholipid hydroperoxide even if they are incorporated in membranes and lipoproteins. Can also reduce fatty acid hydroperoxide, cholesterol hydroperoxide and thymine hydroperoxide. Plays a key role in protecting cells from oxidative damage by preventing membrane lipid peroxidation (By similarity). Required to prevent cells from ferroptosis, a non- apoptotic cell death resulting from an iron-dependent accumulation of lipid reactive oxygen species (By similarity). The presence of s [...] (197 aa)    
Predicted Functional Partners:
GSR
Glutathione reductase; Maintains high levels of reduced glutathione in the cytosol. Belongs to the class-I pyridine nucleotide-disulfide oxidoreductase family.
  
 0.986
GPX2
Glutathione peroxidase; Belongs to the glutathione peroxidase family.
  
 
0.960
GSTA4
Glutathione S-transferase alpha 4.
   
 
 0.957
GPX5
Epididymal secretory glutathione peroxidase; May constitute a glutathione peroxidase-like protective system against peroxide damage in sperm membrane lipids. Since the purified porcine enzyme has very little activity towards hydrogen peroxide or organic hydroperoxides the protective effect is not likely to be exerted by its enzymatic activity. Instead, may protect sperm from premature acrosome reaction in the epididymis by binding to lipid peroxides, which might otherwise interact with phospholipase A2 and induce the acrosome reaction.

PRDX6
Peroxiredoxin-6; Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Can reduce H(2)O(2) and short chain organic, fatty acid, and phospholipid hydroperoxides. Also has phospholipase activity, and can therefore either reduce the oxidized sn-2 fatty acyl grup of phospholipids (peroxidase activity) or hydrolyze the sn-2 ester bond of phospholipids (phospholipase activity). These activities are dependent on binding to phospholipids at acidic pH and to oxidized phospholipds at cytosolic pH. Plays a role [...]

GPX6
Glutathione peroxidase; Belongs to the glutathione peroxidase family.
  
  
0.948
GPX1
Glutathione peroxidase 1; Protects the hemoglobin in erythrocytes from oxidative breakdown.
  
 
0.947
CHAC1
Gamma-glutamylcyclotransferase; Catalyzes the cleavage of glutathione into 5-oxo-L-proline and a Cys-Gly dipeptide. Acts specifically on glutathione, but not on other gamma-glutamyl peptides; Belongs to the gamma-glutamylcyclotransferase family.
     
 0.942
GPX3
Glutathione peroxidase; Belongs to the glutathione peroxidase family.
  
 
0.938
GSTK1
DSBA domain-containing protein.
