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

Sfxn1Sideroflexin-1; Mitochondrial serine transporter that mediates transport of serine into mitochondria, an important step of the one-carbon metabolism pathway. Mitochondrial serine is converted to glycine and formate, which then exits to the cytosol where it is used to generate the charged folates that serve as one-carbon donors. Transports both D- serine and L-serine. Also able to transport other amino-acids, such as alanine (By similarity). May be indirectly involved in the transport of a component required for iron utilization into or out of the mitochondria (By similarity); Belongs t [...] (322 aa)    
Predicted Functional Partners:
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.

Gjb1
Gap junction beta-1 protein; One gap junction consists of a cluster of closely packed pairs of transmembrane channels, the connexons, through which materials of low MW diffuse from one cell to a neighboring cell.
   
  
 0.645
LOC100362384
Ferritin; Stores iron in a soluble, non-toxic, readily available form. Important for iron homeostasis. Iron is taken up in the ferrous form and deposited as ferric hydroxides after oxidation.
      
 0.589
Mtfmt
Methionyl-tRNA formyltransferase, mitochondrial; Formylates methionyl-tRNA in mitochondria. A single tRNA(Met) gene gives rise to both an initiator and an elongator species via an unknown mechanism (By similarity); Belongs to the Fmt family.
   
  
 0.571
Shmt2
Serine hydroxymethyltransferase; Interconversion of serine and glycine. Belongs to the SHMT family.
   
 
 0.533
Shmt1
Serine hydroxymethyltransferase; Interconversion of serine and glycine. Belongs to the SHMT family.
   
 
 0.532
C17h6orf52
Similar to human chromosome 6 open reading frame 52.
      
 0.522
Runx1t1
RUNX1 partner transcriptional co-repressor 1.
   
    0.485
Mthfd2l
Probable bifunctional methylenetetrahydrofolate dehydrogenase/cyclohydrolase 2; Belongs to the tetrahydrofolate dehydrogenase/cyclohydrolase family.
      
 0.479
Iscu
Similar to nitrogen fixation cluster-like (Predicted), isoform CRA_b; 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.
