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

PPO2Prophenoloxidase 2 (PPO2) encodes a protein stored in large crystals in the crystal cells (a type of hemocyte cell) that is involved in the melanization reaction. It contributes to melanization around wounds and wasp encapsulation and is thought to be activated by proteolytic cleavage by the product of Hayan. (684 aa)    
Predicted Functional Partners:
PPO1
Prophenoloxidase 1 (PPO1) encodes a protein produced by crystal cells (a type of hemocyte cell) and is involved in the melanization reaction, notably upon wounding. It is thought to be activated by proteolytic cleavage by the serine protease encoded by Hayan.

Spn27A
Serine protease inhibitor 27A; Serine protease inhibitor that functions in embryonic dorsoventral patterning and the melanization immune response. Regulates dorsoventral axis formation during early development by inhibiting the serine protease easter, and is therefore important for restricting activity of the Toll signaling pathway to the ventral part of the embryo. Also plays an essential role in the melanization immune response to both physical wounding and septic infection using certain bacteria and fungi. Negatively regulates the Hayan- dependent prophenoloxidase 1 (PPO1)-activatin [...]

Hml
Hemolectin, isoform A; Hemolectin (Hml) encodes a large multidomain protein produced by hemocytes and involved in the clotting reaction.
   
 
 0.702
Pxn
Peroxidasin; Plays a role in extracellular matrix consolidation, phagocytosis and defense.
   
 
 0.692
Hayan
Serine protease Hayan; Serine protease which, by converting prophenoloxidase 1 (PPO1) into its active form, plays an essential role in the melanization immune response to physical or septic wounding. May function in diverse PPO1-activating cascades that are negatively controlled by different serpin proteins; Spn27A and Spn28D in the hemolymph, and Spn28D and Spn77BA in the trachea. Also required in the systematic wound response by mediating the redox-dependent activation of the JNK cytoprotective cascade in neuronal tissues after integument wounding; Belongs to the peptidase S1 family.

NimC1
Nimrod C1, isoform B; It is involved in the biological process described with: defense response to bacterium; phagocytosis.
   
  
 0.657
yellow-f
L-dopachrome tautomerase yellow-f; Tautomerization of L-dopachrome with decarboxylation to give 5,6-dihydroxyindole (DHI). Also catalyzes the tautomerization of the methyl ester of L-dopachrome and dopamine chrome. May play a role in melanization reactions during late pupal and adult stages. May play a role in melanization reactions during larval and early pupal stages. Belongs to the major royal jelly protein family.
    
 
 0.639
Had2
Beta hydroxy acid dehydrogenase 2; 3-hydroxyacyl-CoA dehydrogenase activity. It is involved in the biological process described with: fatty acid metabolic process; oxidation-reduction process.
  
  
 0.633
Tep1
Thioester-containing protein 1; Endopeptidase inhibitor activity. It is involved in the biological process described with: innate immune response.
      
 0.608
Glt
Glutactin (Glt) encodes a secreted protein that belongs to the family of cholinesterase/carboxylesterase-like proteins but lacks the catalytically active residues. It forms part of the basement membrane and regulates axonal outgrowth.
