STRING protein interaction network
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

Gene Fusion
SPCC1183.03c.1Frataxin 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 (158 aa)    
Predicted Functional Partners:
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 [...]
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
Protein isd11; Required for mitochondrial iron-sulfur (Fe-S) protein biosynthesis
Ferrochelatase, mitochondrial; Catalyzes the ferrous insertion into protoporphyrin IX; Belongs to the ferrochelatase family
Electron transfer protein 1, mitochondrial; Mitochondrial type I (2Fe-2S) ferredoxin Etp1/ cytochrome oxidase cofactor Cox15, fusion protein
J-type co-chaperone jac1, mitochondrial; Co-chaperone required for the assembly of iron-sulfur (Fe/S) clusters in mitochondria. Stimulates the ATPase activity of the mitochondrial Hsp70 chaperone (mtHsp70). Binds to the substrate protein isu1 and targets it to mtHsp70 (By similarity)
Iron-sulfur clusters transporter atm1, mitochondrial; Performs an essential function in the generation of cytoplasmic iron-sulfur proteins by mediating the ATP-dependent export of Fe/S cluster precursors synthesized by NFS1 and other mitochondrial proteins. Hydrolyzes ATP. Binds glutathione and may function by transporting a glutathione-conjugated iron-sulfur compound. Also has an indirect role in vacuolar function where it is required for fluid-phase endocytosis
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
NifU-like protein iron-sulfur cluster assembly protein Nfu1 (predicted); Belongs to the NifU family
Putative transferase caf17, mitochondrial; Mitochondrial iron-sulfur cluster biogenesis protein Iba57 (predicted)
