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

rpsA30S ribosomal subunit protein S1; Required for translation of most natural mRNAs except for leaderless mRNA. Binds mRNA upstream of the Shine- Dalgarno (SD) sequence and helps it bind to the 30S ribosomal subunit; acts as an RNA chaperone to unfold structured mRNA on the ribosome but is not essential for mRNAs with strong SDs and little 5'-UTR structure, thus it may help fine-tune which mRNAs that are translated. Unwinds dsRNA by binding to transiently formed ssRNA regions; binds about 10 nucleotides. Has a preference for polypyrimidine tracts. Negatively autoregulates its own translat [...] (557 aa)    
Predicted Functional Partners:
rpsB
30S ribosomal subunit protein S2; Required for ribosomal protein S1 to bind to the 30S subunit.
  
 0.999
rpsD
30S ribosomal subunit protein S4; One of two assembly initiator proteins for the 30S subunit, it binds directly to 16S rRNA where it nucleates assembly of the body of the 30S subunit. Plays a role in mRNA unwinding by the ribosome, possibly by forming part of a processivity clamp. Also functions as a rho-dependent antiterminator of rRNA transcription, increasing the synthesis of rRNA under conditions of excess protein, allowing a more rapid return to homeostasis. Binds directly to RNA polymerase; Belongs to the universal ribosomal protein uS4 family.
   
 0.999
rpsK
30S ribosomal subunit protein S11; Located on the platform of the 30S subunit, it bridges several disparate RNA helices of the 16S rRNA. Forms part of the Shine- Dalgarno cleft in the 70S ribosome (By similarity); Belongs to the universal ribosomal protein uS11 family.
   
 0.999
rpsM
30S ribosomal subunit protein S13; Located at the top of the head of the 30S subunit, it contacts several helices of the 16S rRNA. Contacts the tRNAs in the A and P sites. Belongs to the universal ribosomal protein uS13 family.
   
 0.999
rpsE
30S ribosomal subunit protein S5; With S4 and S12 plays an important role in translational accuracy. Many suppressors of streptomycin-dependent mutants of protein S12 are found in this protein, some but not all of which decrease translational accuracy (ram, ribosomal ambiguity mutations). The physical location of this protein suggests it may also play a role in mRNA unwinding by the ribosome, possibly by forming part of a processivity clamp.
  
 0.999
rpsH
30S ribosomal subunit protein S8; One of the primary rRNA binding proteins, it binds directly to 16S rRNA central domain where it helps coordinate assembly of the platform of the 30S subunit; Belongs to the universal ribosomal protein uS8 family.
  
 0.999
rpsQ
30S ribosomal subunit protein S17; One of the primary rRNA binding proteins, it binds specifically to the 5'-end of 16S ribosomal RNA. Also plays a role in translational accuracy; neamine-resistant ribosomes show reduced neamine-induced misreading in vitro.
  
 0.999
rpsC
30S ribosomal subunit protein S3; Binds the lower part of the 30S subunit head. Binds mRNA in the 70S ribosome, positioning it for translation (By similarity). Belongs to the universal ribosomal protein uS3 family.
 
 0.999
rplD
50S ribosomal subunit 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. Forms part of the polypeptide exit tunnel. Belongs to the universal ribosomal protein uL4 family.
  
 0.999
rpsJ
30S ribosomal subunit protein S10; Involved in the binding of tRNA to the ribosomes. In addition, in complex with NusB, is involved in the regulation of ribosomal RNA (rRNA) biosynthesis by transcriptional antitermination. S10 binds RNA non-specifically and increases the affinity of NusB for the boxA RNA sequence. S10 may constitute the critical antitermination component of the NusB-S10 complex. Belongs to the universal ribosomal protein uS10 family.
