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

PRB4Basic salivary proline-rich protein 4; Proline rich protein BstNI subfamily 4. (247 aa)    
Predicted Functional Partners:
PRB1
Basic salivary proline-rich protein 1; Proline rich protein BstNI subfamily 1.
   
  
 0.999
PRB3
Basic salivary proline-rich protein 3; Acts as a receptor for the Gram-negative bacterium F.nucleatum.
   
  
0.999
PRH1
Proline rich protein HaeIII subfamily 1.
   
  
 0.924
PRH2
Salivary acidic proline-rich phosphoprotein 1/2; PRP's act as highly potent inhibitors of crystal growth of calcium phosphates. They provide a protective and reparative environment for dental enamel which is important for the integrity of the teeth.
      
 0.916
RB1
Retinoblastoma-associated protein; Key regulator of entry into cell division that acts as a tumor suppressor. Promotes G0-G1 transition when phosphorylated by CDK3/cyclin-C. Acts as a transcription repressor of E2F1 target genes. The underphosphorylated, active form of RB1 interacts with E2F1 and represses its transcription activity, leading to cell cycle arrest. Directly involved in heterochromatin formation by maintaining overall chromatin structure and, in particular, that of constitutive heterochromatin by stabilizing histone methylation. Recruits and targets histone methyltransfer [...]
      
 0.780
C4BPA
C4b-binding protein alpha chain; Controls the classical pathway of complement activation. It binds as a cofactor to C3b/C4b inactivator (C3bINA), which then hydrolyzes the complement fragment C4b. It also accelerates the degradation of the C4bC2a complex (C3 convertase) by dissociating the complement fragment C2a. Alpha chain binds C4b. It interacts also with anticoagulant protein S and with serum amyloid P component.
      
 0.750
SMR3B
Submaxillary gland androgen regulated protein 3B; Belongs to the PROL1/PROL3 family.
   
 
 0.559
STATH
Statherin; Salivary protein that stabilizes saliva supersaturated with calcium salts by inhibiting the precipitation of calcium phosphate salts. It also modulates hydroxyapatite crystal formation on the tooth surface.
   
  
 0.522
OR5M8
Olfactory receptor 5M8; Odorant receptor; Belongs to the G-protein coupled receptor 1 family.
      
 0.506
SFTPA2
Surfactant protein A2.
      
 0.495
