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

rplU50S ribosomal protein L21; This protein binds to 23S rRNA in the presence of protein L20; Belongs to the bacterial ribosomal protein bL21 family. (170 aa)    
Predicted Functional Partners:
rpmA
COG211 Ribosomal protein L27 [Translation, ribosomal structure and biogenesis]; Belongs to the bacterial ribosomal protein bL27 family.
 
 
 0.999
rplS
Ribosomal protein L19; This protein is located at the 30S-50S ribosomal subunit interface and may play a role in the structure and function of the aminoacyl-tRNA binding site.
  
 
 0.997
rpmB
COG227 Ribosomal protein L28 [Translation, ribosomal structure and biogenesis]; Belongs to the bacterial ribosomal protein bL28 family.
  
 
 0.997
rpsP
COG228 Ribosomal protein S16 [Translation, ribosomal structure and biogenesis]; Belongs to the bacterial ribosomal protein bS16 family.
 
 
 0.997
rpsT
30s Ribosomal protein S20; Binds directly to 16S ribosomal RNA.
 
 
 0.997
rpsI
COG103 Ribosomal protein S9 [Translation, ribosomal structure and biogenesis]; Belongs to the universal ribosomal protein uS9 family.
  
 
 0.997
rplM
50S ribosomal protein L13; This protein is one of the early assembly proteins of the 50S ribosomal subunit, although it is not seen to bind rRNA by itself. It is important during the early stages of 50S assembly.
  
 
 0.997
rplX
50S ribosomal protein L24; One of the proteins that surrounds the polypeptide exit tunnel on the outside of the subunit.
  
 
 0.997
rplB
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. Belongs to the universal ribosomal protein uL2 family.
  
 
 0.997
rplT
50S ribosomal protein L20; Binds directly to 23S ribosomal RNA and is necessary for the in vitro assembly process of the 50S ribosomal subunit. It is not involved in the protein synthesizing functions of that subunit.
