STRINGSTRING
EPS1 protein (Saccharomyces cerevisiae) - STRING interaction network
"EPS1" - ER protein with chaperone and co-chaperone activity, involved in retention of resident ER proteins 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

Score
EPS1ER protein with chaperone and co-chaperone activity, involved in retention of resident ER proteins; has a role in recognizing proteins targeted for ER-associated degradation (ERAD), member of the protein disulfide isomerase family; Acts as a membrane-bound chaperone in endoplasmic reticulum quality control. Probably facilitates presentation of substrate to membrane-bound components of the degradation machinery (701 aa)    
Predicted Functional Partners:
GLT1
NAD(+)-dependent glutamate synthase (GOGAT), synthesizes glutamate from glutamine and alpha-ketoglutarate; with Gln1p, forms the secondary pathway for glutamate biosynthesis from ammonia; expression regulated by nitrogen source; Forms L-glutamate from L-glutamine and 2-oxoglutarate. Represents an alternative pathway to L-glutamate dehydrogenase for the biosynthesis of L-glutamate. Participates with glutamine synthetase in ammonia assimilation processes. The enzyme is specific for NADH, L-glutamine and 2-oxoglutarate (2145 aa)

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)

TSA1
Thioredoxin peroxidase, acts as both a ribosome-associated and free cytoplasmic antioxidant; self-associates to form a high-molecular weight chaperone complex under oxidative stress; deletion results in mutator phenotype; Physiologically important antioxidant which constitutes an enzymatic defense against sulfur-containing radicals. Can provide protection against a thiol-containing oxidation system but not against an oxidation system without thiol (196 aa)
   
 
  0.878
TSA2
Stress inducible cytoplasmic thioredoxin peroxidase; cooperates with Tsa1p in the removal of reactive oxygen, nitrogen and sulfur species using thioredoxin as hydrogen donor; deletion enhances the mutator phenotype of tsa1 mutants; Reduces peroxides. May play an important role in eliminating peroxides generated during metabolism (By similarity) (196 aa)
   
 
  0.878
PRX1
Mitochondrial peroxiredoxin (1-Cys Prx) with thioredoxin peroxidase activity, has a role in reduction of hydroperoxides; reactivation requires Trr2p and glutathione; induced during respiratory growth and oxidative stress; phosphorylated; Has a thioredoxin peroxidase activity with a role in reduction of hydroperoxides (261 aa)
   
 
  0.878
TRR2
Mitochondrial thioredoxin reductase involved in protection against oxidative stress, required with Glr1p to maintain the redox state of Trx3p; contains active-site motif (CAVC) present in prokaryotic orthologs; binds NADPH and FAD; Acts on mitochondrial thioredoxin 3. Implicated in the defense against oxidative stress (342 aa)
   
 
  0.877
TRR1
Cytoplasmic thioredoxin reductase, key regulatory enzyme that determines the redox state of the thioredoxin system, which acts as a disulfide reductase system and protects cells against both oxidative and reductive stress; Acts on thioredoxins 1 and 2 (319 aa)
   
 
  0.877
SEC61
Essential subunit of Sec61 complex (Sec61p, Sbh1p, and Sss1p); forms a channel for SRP-dependent protein import and retrograde transport of misfolded proteins out of the ER; with Sec63 complex allows SRP-independent protein import into ER; Part of the Sec61 complex, which is the major component of a channel-forming translocon complex that mediates protein translocation across the endoplasmic reticulum (ER). The functional states of the translocon complex include co- and post- translational ER import, cotranslational membrane protein integration and retrograde transport of misfolded pro [...] (480 aa)
     
 
  0.876
HSC82
Cytoplasmic chaperone of the Hsp90 family, redundant in function and nearly identical with Hsp82p, and together they are essential; expressed constitutively at 10-fold higher basal levels than HSP82 and induced 2-3 fold by heat shock; Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved in cell cycle control and signal transduction such as CNA2. Undergoes a functional cycle that is linked to its ATPase activity (By similarity). Interacts dynamically with various co-chaperones that modulate its substrate reco [...] (705 aa)

MPD1
Member of the protein disulfide isomerase (PDI) family; interacts with and inhibits the chaperone activity of Cne1p; MPD1 overexpression in a pdi1 null mutant suppresses defects in Pdi1p functions such as carboxypeptidase Y maturation; Participates in the folding of proteins containing disulfide bonds (318 aa)
