GRX5 protein (Saccharomyces cerevisiae) - STRING interaction network
"GRX5" - Hydroperoxide and superoxide-radical responsive glutathione-dependent oxidoreductase in Saccharomyces cerevisiae
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 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
protein homology
Your Input:
Gene Fusion
GRX5Hydroperoxide and superoxide-radical responsive glutathione-dependent oxidoreductase; mitochondrial matrix protein involved in the synthesis/assembly of iron-sulfur centers; monothiol glutaredoxin subfamily member along with Grx3p and Grx4p; Monothiol glutaredoxin involved in iron-sulfur biogenesis. Required for normal iron homeostasis. Protects cells against oxidative damage due to reactive oxygen species (150 aa)    
Predicted Functional Partners:
Cytoplasmic glutaredoxin, thioltransferase, glutathione-dependent disulfide oxidoreductase involved in maintaining redox state of target proteins, also exhibits glutathione peroxidase activity, expression induced in response to stress; Component of the glutathione system which performs several activities such as glutathione-dependent oxidoreductase, glutathione peroxidase and glutathione S-transferase (GST) activity. The disulfide bond functions as an electron carrier in the glutathione-dependent synthesis of deoxyribonucleotides by the enzyme ribonucleotide reductase. In addition, it [...] (143 aa)
Protein involved in mitochondrial function or organization; null mutant displays elevated frequency of mitochondrial genome loss (118 aa)
Protein involved in negative regulation of iron regulon transcription; forms an iron independent complex with Fra2p, Grx3p, and Grx4p; null mutant fails to repress iron regulon and is sensitive to nickel; Involved in the regulation of the iron regulon in response to decreased mitochondrial iron-sulfur cluster synthesis. May be involved in mitochondrial organization and biogenesis (120 aa)
Conserved component of an early step in the cytosolic Fe-S protein assembly (CIA) machinery; contains an Fe-S cluster that receives electrons from NADPH via the action of Tah18p; ortholog of human Ciapin1; Component of the cytosolic iron-sulfur (Fe-S) protein assembly (CIA) machinery. Required for the maturation of extramitochondrial Fe-S proteins. Part of an electron transfer chain functioning in an early step of cytosolic Fe-S biogenesis. Electrons are transferred to the Fe-S cluster from NADPH via the FAD- and FMN-containing protein TAH18. Has anti-apoptotic effects in the cell. Inv [...] (348 aa)
Protein required for maturation of mitochondrial [4Fe-4S] proteins; functions in a complex with Isa1p and possibly Iba57p; localizes to the mitochondrial intermembrane space, overexpression of ISA2 suppresses grx5 mutations; Involved in the assembly of mitochondrial and cytoplasmic iron-sulfur proteins. Probably involved in the binding of an intermediate of Fe/S cluster assembly (185 aa)
Mitochondrial hsp70-type molecular chaperone, required for assembly of iron/sulfur clusters into proteins at a step after cluster synthesis, and for maturation of Yfh1p, which is a homolog of human frataxin implicated in Friedreich’s ataxia; Has a role in mitochondrial iron homeostasis. Appears to be involved in the processing of the intermediate form of the frataxin homolog YFH1. Required for the assembly of iron-sulfur (Fe/S) clusters in mitochondria (657 aa)
Putative protein of unknown function; similar to S. pombe uvi31 which is a putative DNA repair protein (110 aa)
Protein required for maturation of mitochondrial [4Fe-4S] proteins; functions in a complex with Isa2p and possibly Iba57p; isa1 deletion causes loss of mitochondrial DNA and respiratory deficiency; depletion reduces growth on nonfermentable carbon s /.../; functional ortholog of bacterial A-type ISC proteins; Involved in the assembly of mitochondrial and cytoplasmic iron-sulfur proteins. Probably involved in the binding of an intermediate of Fe/S cluster assembly (250 aa)
Gamma glutamylcysteine synthetase catalyzes the first step in glutathione (GSH) biosynthesis; expression induced by oxidants, cadmium, and mercury (678 aa)
N-succinyl-5-aminoimidazole-4-carboxamide ribotide (SAICAR) synthetase, required for ’de novo’ purine nucleotide biosynthesis; red pigment accumulates in mutant cells deprived of adenine (306 aa)
