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

Predicted Functional Partners:
DEFB106A
Defensin beta 106A.
      
 0.848
DEFB106B
Beta-defensin 106; Has antibacterial activity. Acts as a ligand for C-C chemokine receptor CCR2. Belongs to the beta-defensin family.
      
 0.836
DEFB105A
Beta-defensin 105; Has antibacterial activity.
      
 0.831
DEFB107A
Beta-defensin 107; Has antibacterial activity.
      
 0.824
DEFB103A
Beta-defensin 103; Exhibits antimicrobial activity against Gram-positive bacteria S.aureus and S.pyogenes, Gram-negative bacteria P.aeruginosa and E.coli and the yeast C.albicans. Kills multiresistant S.aureus and vancomycin-resistant E.faecium. No significant hemolytic activity was observed.
      
 0.823
DEFB4A
Beta-defensin 4A; Exhibits antimicrobial activity against Gram-negative bacteria and Gram-positive bacteria. May act as a ligand for C-C chemokine receptor CCR6. Can bind to both human and mouse CCR6 and induce chemotactic activity of CCR6-expressing cells. Belongs to the beta-defensin family. LAP/TAP subfamily.
   
  
 0.798
DEFB104A
Beta-defensin 104; Has antimicrobial activity. Synergistic effects with lysozyme and DEFB103; Belongs to the beta-defensin family.
      
 0.771
DEFB126
Beta-defensin 126; Highly glycosylated atypical beta-defensin involved in several aspects of sperm function. Facilitates sperm transport in the female reproductive tract and contributes to sperm protection against immunodetection; both functions are probably implicating the negative surface charge provided by its O-linked oligosaccharides in the sperm glycocalyx. Involved in binding of sperm to oviductal epithelial cells to form a sperm reservoir until ovulation. Release from the sperm surface during capacitation and ovaluation by an elevation of oviductal fluid pH is unmasking other s [...]

 0.599
PRR23D1
Proline rich 23 domain containing 1.
      
 0.599
