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

splBSerine protease SplB; Serine protease that cleaves specifically after the sequence Trp-Glu-Leu-Gln; Belongs to the peptidase S1B family. (240 aa)    
Predicted Functional Partners:
splA
Serine protease SplA.
 
  
0.968
splF
Serine protease SplF, putative.
  
  
0.756
splC
Serine protease SplC.
 
  
0.755
splD
Serine protease SplD.
 
  
0.575
sspB
Cysteine protease precursor, putative; Cysteine protease that plays an important role in the inhibition of host innate immune response. Degrades host elastin, fibrogen, fibronectin and kininogen. Blocks phagocytosis of opsonised S. aureus by neutrophils and monocytes by inducing their death in a proteolytic activity-dependent manner. Decreases surface expression of the 'don't eat me' signal CD31 on neutrophils. Cleaves host galectin- 3/LGALS3, thereby inhibiting the neutrophil-activating ability of the lectin.
   
  
 0.553
splE
Serine protease SplE.
  
 
0.511
hlgB
Leukocidin f subunit precursor; Toxin that seems to act by forming pores in the membrane of the cell. Has a hemolytic and a leucotoxic activity (By similarity). Belongs to the aerolysin family.
   
  
 0.471
hlgC
Leukocidin s subunit precursor, putative; Toxin that seems to act by forming pores in the membrane of the cell. Has a hemolytic and a leucotoxic activity (By similarity). Belongs to the aerolysin family.
   
  
 0.463
sspC
Cysteine protease, putative; Specifically inhibits the cysteine protease staphopain B (SspB) by blocking the active site of the enzyme. Probably required to protect cytoplasmic proteins from being degraded by prematurely activated/folded prostaphopain B. Also involved in growth capacity, viability and bacterial morphology; Belongs to the protease inhibitor I57 (SspC) family.
   
  
 0.447
lip2
Lipase precursor.
  
  
 0.441
