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

ABCB7ATP-binding cassette sub-family B member 7, mitochondrial; Could be involved in the transport of heme from the mitochondria to the cytosol. Plays a central role in the maturation of cytosolic iron-sulfur (Fe/S) cluster-containing proteins. (753 aa)    
Predicted Functional Partners:
NUBP1
Cytosolic Fe-S cluster assembly factor NUBP1; Component of the cytosolic iron-sulfur (Fe/S) protein assembly (CIA) machinery. Required for maturation of extramitochondrial Fe-S proteins. The NUBP1-NUBP2 heterotetramer forms a Fe-S scaffold complex, mediating the de novo assembly of an Fe-S cluster and its transfer to target apoproteins. Implicated in the regulation of centrosome duplication (By similarity). Negatively regulates cilium formation and structure (By similarity).
   
 0.938
ALAS2
5-aminolevulinate synthase, erythroid-specific, mitochondrial; 5'-aminolevulinate synthase 2.
   
  
 0.907
FECH
Ferrochelatase, mitochondrial; Catalyzes the ferrous insertion into protoporphyrin IX; Belongs to the ferrochelatase family.
   
 
 0.906
SLC25A37
Mitoferrin-1; Mitochondrial iron transporter that specifically mediates iron uptake in developing erythroid cells, thereby playing an essential role in heme biosynthesis. The iron delivered into the mitochondria, presumably as Fe(2+), is then probably delivered to ferrochelatase to catalyze Fe(2+) incorporation into protoprophyrin IX to make heme (By similarity).
    
 
 0.886
ACO1
Cytoplasmic aconitate hydratase; Iron sensor. Binds a 4Fe-4S cluster and functions as aconitase when cellular iron levels are high. Functions as mRNA binding protein that regulates uptake, sequestration and utilization of iron when cellular iron levels are low. Binds to iron-responsive elements (IRES) in target mRNA species when iron levels are low. Binding of a 4Fe-4S cluster precludes RNA binding.

NUBP2
Cytosolic Fe-S cluster assembly factor NUBP2; Component of the cytosolic iron-sulfur (Fe/S) protein assembly (CIA) machinery. Required for maturation of extramitochondrial Fe-S proteins. The NUBP1-NUBP2 heterotetramer forms a Fe-S scaffold complex, mediating the de novo assembly of an Fe-S cluster and its transfer to target apoproteins. Negatively regulates cilium formation and structure.

GLRX5
Glutaredoxin-related protein 5, mitochondrial; Monothiol glutaredoxin involved in the biogenesis of iron- sulfur clusters. Involved in protein lipoylation, acting in the pathway that provides an iron-sulfur cluster to lipoate synthase. Required for normal iron homeostasis. Required for normal regulation of hemoglobin synthesis by the iron- sulfur protein ACO1. May protect cells against apoptosis due to reactive oxygen species and oxidative stress (By similarity).
   
 
 0.825
TMEM14C
Transmembrane protein 14C; Required for normal heme biosynthesis.
   
  
 0.811
ABCB10
ATP-binding cassette sub-family B member 10, mitochondrial; May mediate critical mitochondrial transport functions related to heme biosynthesis; Belongs to the ABC transporter superfamily. ABCB family. Mitochondrial peptide exporter (TC 3.A.1.212) subfamily.
   
0.791
SLC25A38
Mitochondrial glycine transporter; Mitochondrial glycine transporter that imports glycine into the mitochondrial matrix. Plays an important role in providing glycine for the first enzymatic step in heme biosynthesis, the condensation of glycine with succinyl-CoA to produce 5-aminolevulinate (ALA) in the mitochondrial matrix. Required during erythropoiesis. Belongs to the mitochondrial carrier (TC 2.A.29) family. SLC25A38 subfamily.
