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 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

smpBSsra-binding protein; Required for rescue of stalled ribosomes mediated by trans- translation. Binds to transfer-messenger RNA (tmRNA), required for stable association of tmRNA with ribosomes. tmRNA and SmpB together mimic tRNA shape, replacing the anticodon stem-loop with SmpB. tmRNA is encoded by the ssrA gene; the 2 termini fold to resemble tRNA(Ala) and it encodes a 'tag peptide', a short internal open reading frame. During trans-translation Ala-aminoacylated tmRNA acts like a tRNA, entering the A-site of stalled ribosomes, displacing the stalled mRNA. The ribosome then switches to [...] (159 aa)    
Predicted Functional Partners:
rplM
Large subunit 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
 
 
 0.995
rplS
Large subunit 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
 
 
 0.995
rpsC
Small subunit ribosomal protein s3; Binds the lower part of the 30S subunit head. Binds mRNA in the 70S ribosome, positioning it for translation
 
 
 0.994
rplP
Large subunit ribosomal protein l16; Binds 23S rRNA and is also seen to make contacts with the A and possibly P site tRNAs
 
 
 0.994
rpsM
Small subunit 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. Contacts the tRNAs in the A and P-sites
 
 
 0.993
rpsB
Small subunit ribosomal protein s2; Belongs to the universal ribosomal protein uS2 family
 
 
 0.993
rplD
Large subunit ribosomal protein l4; One of the primary rRNA binding proteins, this protein initially binds near the 5'-end of the 23S rRNA. It is important during the early stages of 50S assembly. It makes multiple contacts with different domains of the 23S rRNA in the assembled 50S subunit and ribosome (By similarity). Forms part of the polypeptide exit tunnel
 
 
 0.990
rplT
Large subunit 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
  
 
 0.990
rpsS
Small subunit ribosomal protein s19; Protein S19 forms a complex with S13 that binds strongly to the 16S ribosomal RNA
 
 
 0.988
rpsI
Small subunit ribosomal protein s9; Belongs to the universal ribosomal protein uS9 family
  
 
 0.987
