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

isu1
Iron sulfur cluster assembly protein 1, mitochondrial; Scaffold protein for the de novo synthesis of iron-sulfur (Fe-S) clusters within mitochondria, which is required for maturation of both mitochondrial and cytoplasmic [2Fe-2S] and [4Fe-4S] proteins. First, a [2Fe-2S] cluster is transiently assembled on the scaffold protein isu1. In a second step, the cluster is released from isu1, transferred to a glutaredoxin, followed by the formation of mitochondrial [2Fe-2S] proteins, the synthesis of [4Fe-4S] clusters and their target-specific insertion into the recipient apoproteins. Cluster a [...]

grx5
Monothiol glutaredoxin-5; Thiol reductase involved in the biogenesis of iron-sulfur clusters. Required for normal iron homeostasis. Required for integrity of mitochondrial DNA. May play a crucial role in responses to nitrosative and osmotic stresses; Belongs to the glutaredoxin family. Monothiol subfamily.

mge1
GrpE protein homolog, mitochondrial; Essential component of the PAM complex, a complex required for the translocation of transit peptide-containing proteins from the inner membrane into the mitochondrial matrix in an ATP-dependent manner. Seems to control the nucleotide-dependent binding of ssc1 to substrate proteins (By similarity).

nfs1
Probable cysteine desulfurase, mitochondrial; Catalyzes the removal of elemental sulfur from cysteine to produce alanine. It supplies the inorganic sulfur for iron-sulfur (Fe- S) clusters. Plays a role in both tRNA-processing and mitochondrial metabolism. Involved in the 2-thio-modification of both 5- carboxymethylaminomethyl-2-thiouridine in mitochondrial tRNAs and 5- methoxycarbonylmethyl-2-thiouridine (mcm5s2U) in cytoplasmic tRNAs. Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. NifS/IscS subfamily.

fxn1
Frataxin homolog, mitochondrial; Promotes the biosynthesis of heme as well as the assembly and repair of iron-sulfur clusters by delivering Fe(2+) to proteins involved in these pathways. May play a role in the protection against iron-catalyzed oxidative stress through its ability to catalyze the oxidation of Fe(2+) to Fe(3+). May be able to store large amounts of the metal in the form of a ferrihydrite mineral by oligomerization (By similarity); Belongs to the frataxin family.
