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

nusATranscription termination/antitermination L factor; Participates in both transcription termination and antitermination. Involved in a variety of cellular and viral termination and antitermination processes, such as Rho-dependent transcriptional termination, intrinsic termination, and phage lambda N- mediated transcriptional antitermination. Also important for coordinating the cellular responses to DNA damage by coupling the processes of nucleotide excision repair and translesion synthesis to transcription. (495 aa)    
Predicted Functional Partners:
rpoA
RNA polymerase, alpha subunit; DNA-dependent RNA polymerase (RNAP) catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. This subunit plays an important role in subunit assembly since its dimerization is the first step in the sequential assembly of subunits to form the holoenzyme.

rpoB
RNA polymerase, beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 0.999
rpoC
RNA polymerase, beta prime subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.

nusG
Transcription termination factor; Participates in transcription elongation, termination and antitermination. In the absence of Rho, increases the rate of transcription elongation by the RNA polymerase (RNAP), probably by partially suppressing pausing. In the presence of Rho, modulates most Rho-dependent termination events by interacting with the RNAP to render the complex more susceptible to the termination activity of Rho. May be required to overcome a kinetic limitation of Rho to function at certain terminators. Also involved in ribosomal RNA and phage lambda N-mediated transcription [...]

infB
Translation initiation factor IF-2; One of the essential components for the initiation of protein synthesis. May protect N-formylmethionyl-tRNA(fMet) from spontaneous hydrolysis. Promotes N-formylmethionyl-tRNA(fMet) binding to the 30S pre-initiation complex (PIC). Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex. Upon addition of the 50S ribosomal subunit, IF-1, IF-2 and IF-3 are released leaving the mature 70S translation initiation complex. Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase fam [...]

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.
 
 0.996
rpsB
30S ribosomal subunit protein S2; Required for ribosomal protein S1 to bind to the 30S subunit.
 
 
 0.993
rimP
Ribosome maturation factor for 30S subunits; Required for maturation of 30S ribosomal subunits, probably at a late stage of ribosomal protein binding, while Era is associated and after RimM.
  
  
 0.993
rplK
50S ribosomal subunit protein L11; Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors; Belongs to the universal ribosomal protein uL11 family.
  
 
 0.992
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.
