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

SelRMethionine-R-sulfoxide reductase B1; Methionine-sulfoxide reductase that specifically reduces methionine (R)-sulfoxide back to methionine. While in many cases methionine oxidation is the result of random oxidation following oxidative stress, methionine oxidation is also a post-translational modification that takes place on specific residues. Acts as a regulator of actin assembly by reducing methionine (R)-sulfoxide mediated by Mical on actin thereby promoting filament repolymerization. (208 aa)    
Predicted Functional Partners:
MsrA
Ecdysone-induced protein 28/29kD (Eip71CD) encodes a methionine-S-sulfoxide reductase involved in the response to oxidative stress. It contributes to determination of adult lifespan and neuron projection.
 
 
 0.990
SelT
Thioredoxin reductase-like selenoprotein T homolog CG3887; Probably has thioredoxin reductase-like oxidoreductase activity; Belongs to the SelWTH family. SELT subfamily.
      
 0.883
CG7484
CG7484 protein; Oxidoreductase activity; disulfide oxidoreductase activity. It is involved in the biological process described with: cell redox homeostasis.
      
 0.855
CG42394
MIP05983p.
  
 
 0.852
Trx-2
Thioredoxin-2; Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions. As a reducing substrate of peroxiredoxin 1, thioredoxin 2 is preferred over thioredoxin 1.
  
 0.843
mRpL20
Mitochondrial ribosomal protein L20; rRNA binding; structural constituent of ribosome. It is involved in the biological process described with: mitochondrial translation; translation; ribosomal large subunit assembly; Belongs to the bacterial ribosomal protein bL20 family.
  
 
 0.776
Mical
[F-actin]-monooxygenase Mical; Monooxygenase that promotes depolymerization of F-actin by mediating oxidation of specific methionine residues on actin. Acts by modifying actin subunits at 'Met-44' and 'Met-47' through the addition of oxygen to form methionine-sulfoxide, leading to promote actin filament disassembly and prevent repolymerization. Plays a key role in semaphorin-plexin repulsive axon guidance and cell morphological changes, probably via its ability to modify and regulate actin. Belongs to the Mical family.
   
 
 0.740
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.
  
  
 0.737
PHGPx
PHGPx (PHGPx) encodes a peroxidase involved in intestinal stem cell homeostasis and the response to endoplasmic reticulum stress.
  
  
 0.710
Cat
Catalase (Cat) encodes an enzyme that catalyzes the decomposition of hydrogen peroxide. It reduces the amount of oxidative damage to biomolecules and protects cells from the toxic effects of reactive oxygen species.
