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

fhFrataxin 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. Required for ecdysteroidogenesis in the prothoracic gland which is necessary for larval to pupal transition. Belongs to the frataxin family. (190 aa)    
Predicted Functional Partners:
IscU
Iron-sulfur cluster assembly enzyme; 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.
    
 0.999
bcn92
Protein bcn92; It is involved in the biological process described with: iron-sulfur cluster assembly; Belongs to the complex I LYR family.
   
 0.998
Nfs1
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; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. NifS/IscS subfamily.
   
 0.997
mfrn
Mitoferrin; Mitochondrial iron transporter that mediates iron uptake. Probably required for heme synthesis of hemoproteins and Fe-S cluster assembly; Belongs to the mitochondrial carrier (TC 2.A.29) family.
    
 
 0.977
FeCH
Ferrochelatase, mitochondrial; Catalyzes the ferrous insertion into protoporphyrin IX. Belongs to the ferrochelatase family.
   
 0.969
Ho
Heme oxygenase; Heme oxygenase cleaves the heme ring at the alpha methene bridge to form biliverdin. Biliverdin is subsequently converted to bilirubin by biliverdin reductase.
     
 0.936
Qtzl
Quetzalcoatl, isoform A; Cysteine desulfurase activity; pyridoxal phosphate binding. It is involved in the biological process described with: [2Fe-2S] cluster assembly; iron-sulfur cluster assembly.
   
 
 0.932
Fdx2
Adrenodoxin-like protein 2, mitochondrial; Required for ecdysteroidogenesis in the prothoracic gland which is necessary for larval to pupal transition. Belongs to the adrenodoxin/putidaredoxin family.
   
 
 0.900
Fdx1
Adrenodoxin-like protein 1, mitochondrial; Required for ecdysteroidogenesis in the prothoracic gland which is necessary for larval to pupal transition. Belongs to the adrenodoxin/putidaredoxin family.
   
 
 0.883
ABCB7
ATP binding cassette subfamily B member 7 (ABCB7) encodes a transporter that likely dimerizes to form a functional transporter. It may act in the mitochondria to transport substrates necessary for the maturation of ICS proteins, which are involved in iron homeostasis.
