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

Sps2Selenide, water dikinase 2; Selenophosphate synthetase 2 (Sps2) is essential for selenoprotein biosynthesis. It encodes an enzyme that catalyzes the synthesis of selenophosphate from selenide and/or other selenium metabolites. Selenophosphate is an active selenium donor for the formation of selenocysteine. (370 aa)    
Predicted Functional Partners:
SecS
O-phosphoseryl-tRNA(Sec) selenium transferase; Converts O-phosphoseryl-tRNA(Sec) to selenocysteinyl- tRNA(Sec) required for selenoprotein biosynthesis.

Secp43
RE72132p; mRNA binding. It is involved in the biological process described with: mRNA splicing, via spliceosome; mRNA splice site selection.
      
 0.940
Trxr-2
Thioredoxin reductase 2, mitochondrial; Thioredoxin system is a major player in glutathione metabolism, due to the demonstrated absence of a glutathione reductase. Functionally interacts with the Sod/Cat reactive oxidation species (ROS) defense system and thereby has a role in preadult development and life span. Lack of a glutathione reductase suggests antioxidant defense in Drosophila, and probably in related insects, differs fundamentally from that in other organisms; Belongs to the class-I pyridine nucleotide-disulfide oxidoreductase family.
  
 
 0.931
eEFSec
Eukaryotic translation elongation factor, selenocysteine-specific (eEFSec) encodes a protein involved in the incorporation of selenocysteine during protein translation.
     
 0.923
Trxr-1
Thioredoxin reductase 1, mitochondrial; Thioredoxin system is a major player in glutathione metabolism, due to the demonstrated absence of a glutathione reductase. Functionally interacts with the Sod/Cat reactive oxidation species (ROS) defense system and thereby has a role in preadult development and life span. Lack of a glutathione reductase suggests antioxidant defense in Drosophila, and probably in related insects, differs fundamentally from that in other organisms; Belongs to the class-I pyridine nucleotide-disulfide oxidoreductase family.
  
 
 0.917
Sps1
Inactive selenide, water dikinase-like protein; Selenophosphate synthetase 1 (Sps1) encodes a protein that inhibits Gs1 and dmGlut expression, which in turn regulates the intracellular levels of glutamine.
  
  
0.909
Pstk
SD05444p2; tRNA binding.
      
 0.905
Sbp2
SECIS-binding protein 2 (Sbp2) encodes an RNA stem-loop binding protein involved in selenocysteine incorporation at a stop codon (UGA) during translation.
  
  
 0.849
SelG
Selenoprotein G (SelG) encodes a type III Golgi apparatus transmembrane protein. It is implicated in the release of Ca[2+] from the endoplasmic reticulum to the cytosol by regulating the expression of genes participating in the inositol 1,4,5-tris-phosphate pathway.
   
  
 0.740
SerRS-m
Seryl-tRNA synthetase, mitochondrial (SerRS-m) encodes an enzyme that catalyses the aminoacylation of tRNAser with serine, to be used for gene translation during protein synthesis.
