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

Score
pnpAPolynucleotide phosphorylase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction. (757 aa)    
Predicted Functional Partners:
cafA
Ribonuclease G; Family membership.
  
 
 0.963
nusA
N utilization substance protein A; Participates in both transcription termination and antitermination.
 
  
 0.924
deaD3
DeaD3 protein; High confidence in function and specificity.
 
 0.912
infB
Translation initiation factor IF-2; One of the essential components for the initiation of protein synthesis. Protects formylmethionyl-tRNA from spontaneous hydrolysis and promotes its binding to the 30S ribosomal subunits. Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex; Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. IF-2 subfamily.
  
  
 0.906
deaD1
ATP-independent RNA helicase; High confidence in function and specificity; Belongs to the DEAD box helicase family.
 
 
 0.900
deaD2
DeaD2 protein; High confidence in function and specificity; Belongs to the DEAD box helicase family.
 
 
 0.900
sce3615
Unnamed protein product; Family membership.
 
 
 0.900
rho
Transcription termination factor Rho; Facilitates transcription termination by a mechanism that involves Rho binding to the nascent RNA, activation of Rho's RNA- dependent ATPase activity, and release of the mRNA from the DNA template.
  
  
 0.900
rpoB
DNA-directed RNA polymerase; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
  
 0.899
rpoA
DNA-directed RNA polymerase, alpha subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
  
 0.892
