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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

rpl2250S ribosomal protein L22; This protein binds specifically to 23S rRNA. It makes multiple contacts with different domains of the 23S rRNA in the assembled 50S subunit and ribosome (156 aa)    
Predicted Functional Partners:
rps15
30S ribosomal protein S15; Similar to GP:297071 percent identity: 48.34; identified by sequence similarity; putative
 
 
 0.999
rpl21e
50S ribosomal protein L21e; Similar to GP:1215982 percent identity: 39.73; identified by sequence similarity; putative; Belongs to the eukaryotic ribosomal protein eL21 family
   
 
 0.999
rpl31e
50S ribosomal protein L31e; Similar to SP:P04649 PID:1431090 PID:4390 PID:625117 PID:625117 percent identity: 42.25; identified by sequence similarity; putative; Belongs to the eukaryotic ribosomal protein eL31 family
   
 
 0.999
rpl3
50S ribosomal protein L3; One of the primary rRNA binding proteins, it binds directly near the 3'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit
 
 
 0.999
rpl23
50S ribosomal protein L23; Binds to 23S rRNA. One of the proteins that surrounds the polypeptide exit tunnel on the outside of the ribosome
  
 
 0.999
rpl2
50S ribosomal protein L2; One of the primary rRNA binding proteins. Required for association of the 30S and 50S subunits to form the 70S ribosome, for tRNA binding and peptide bond formation. It has been suggested to have peptidyltransferase activity; this is somewhat controversial. Makes several contacts with the 16S rRNA in the 70S ribosome
  
 
 0.999
rps19
30S ribosomal protein S19; Protein S19 forms a complex with S13 that binds strongly to the 16S ribosomal RNA
  
 
 0.999
rps13
30S ribosomal protein S13; Located at the top of the head of the 30S subunit, it contacts several helices of the 16S rRNA. In the 70S ribosome it contacts the 23S rRNA (bridge B1a) and protein L5 of the 50S subunit (bridge B1b), connecting the 2 subunits; these bridges are implicated in subunit movement
 
 
 0.999
rps4
30S ribosomal protein S4; One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the body of the 30S subunit
  
 
 0.999
rps11
30S ribosomal protein S11; Located on the platform of the 30S subunit
 
 
 0.999
