STRINGSTRING
TSA1 protein (Saccharomyces cerevisiae) - STRING interaction network
"TSA1" - Thioredoxin peroxidase, acts as both a ribosome-associated and free cytoplasmic antioxidant 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

TSA1Thioredoxin 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)    
Predicted Functional Partners:
TRX2
Cytoplasmic thioredoxin isoenzyme of the thioredoxin system which protects cells against oxidative and reductive stress, forms LMA1 complex with Pbi2p, acts as a cofactor for Tsa1p, required for ER-Golgi transport and vacuole inheritance; Participates as a hydrogen donor in redox reactions through the reversible oxidation of its active center dithiol to a disulfide, accompanied by the transfer of 2 electrons and 2 protons. It is involved in many cellular processes, including deoxyribonucleotide synthesis, repair of oxidatively damaged proteins, protein folding, sulfur metabolism, and r [...] (104 aa)

  0.998
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)
   
 
  0.994
SRX1
Sulfiredoxin, contributes to oxidative stress resistance by reducing cysteine-sulfinic acid groups in the peroxiredoxin Tsa1p, which is formed upon exposure to oxidants; conserved in higher eukaryotes; Contributes to oxidative stress resistance by reducing cysteine-sulfinic acid formed under exposure to oxidants in the peroxiredoxin TSA1. May catalyze the reduction in a multi-step process by acting both as a specific phosphotransferase and as thioltransferase (127 aa)
     
 
  0.992
AHP1
Thiol-specific peroxiredoxin, reduces hydroperoxides to protect against oxidative damage; function in vivo requires covalent conjugation to Urm1p; Thiol-specific antioxidant protein with alkyl hydroperoxidase activity. Involved in osmotic stress resistance and detoxification of the cell. Preferentially eliminates organic peroxides rather than H(2)O(2). Involved in cellular Mn(2+) homeostasis (176 aa)
     
 
  0.986
CTT1
Cytosolic catalase T, has a role in protection from oxidative damage by hydrogen peroxide; Occurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide (562 aa)
   
  0.984
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)
     
 
  0.969
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)
   
 
  0.964
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)
   
 
0.963
DOT5
Nuclear thiol peroxidase; functions as an alkyl-hydroperoxide reductase during post-diauxic growth; Has a role in telomere silencing, which is the repression of chromatin structure which leads to a stop in the transcription of nearby genes. Also has a role in the regulation of telomere length. Acts as an alkyl-hydroperoxide reductase in the nucleus during post-diauxic growth. Preferentially reduces alkyl-hydroperoxides rather than hydrogen preoxide. Acts as an antioxidant necessary for stationary phase survival (215 aa)
