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

Score
pepAGlutamyl-aminopeptidase; High confidence in function and specificity; Belongs to the peptidase M42 family. (355 aa)    
Predicted Functional Partners:
pepF
PepF protein; Peptidase M3B, oligoendopeptidase F; High confidence in function and specificity.
  
  
 0.834
pepO
Peptidase family M13; High confidence in function and specificity.
      
 0.796
pepT
Peptidase T; Cleaves the N-terminal amino acid of tripeptides. Has a broad specificity for tripeptides with no clear preference for a particular tripeptide. Tripeptides with proline in the second position are an exception and are not hydrolyzed. Does not hydrolyze dipeptides, tetrapeptides, or oligopeptides (By similarity).
  
  
 0.789
pepP
Metallopeptidase family M24; High confidence in function and specificity; Belongs to the peptidase M24B family.
 
  
 0.786
pepN
PepN protein; Aminopeptidase with broad substrate specificity to several peptides. It has more affinity for oligopeptides than for dipeptides. It plays an essential role in the metabolism, it may be involved in nitrogen supply or protein turnover.
     
 0.766
pepV
Dipeptidase; High confidence in function and specificity.
 
   
 0.752
pepXP
X-prolyl dipeptidyl aminopeptidase; Removes N-terminal dipeptides sequentially from polypeptides having unsubstituted N-termini provided that the penultimate residue is proline; Belongs to the peptidase S15 family.
      
 0.736
llmg_0405
Putative secreted protein.
       0.544
trxH
Thioredoxin domain 2; Conserved hypothetical protein.
       0.518
pepQ
Xaa-Pro dipeptidase; High confidence in function and specificity; Belongs to the peptidase M24B family.
 
  
 0.487
