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

TFG2TFIIF (Transcription Factor II) middle subunit; involved in both transcription initiation and elongation of RNA polymerase II; homologous to human RAP30. (400 aa)    
Predicted Functional Partners:
RPB5
RNA polymerase subunit ABC27; common to RNA polymerases I, II, and III; contacts DNA and affects transactivation; Belongs to the archaeal RpoH/eukaryotic RPB5 RNA polymerase subunit family.
   
 0.999
RPO21
RNA polymerase II largest subunit B220; part of central core; phosphorylation of C-terminal heptapeptide repeat domain regulates association with transcription and splicing factors; similar to bacterial beta-prime.
    
 0.999
RPB7
RNA polymerase II subunit B16; forms dissociable heterodimer with Rpb4p; Rpb4/7 dissociates from RNAPII as Ser2 CTD phosphorylation increases; Rpb4/7 regulates cellular lifespan via mRNA decay process; involved in recruitment of 3'-end processing factors to transcribing RNA polymerase II complex, export of mRNA to cytoplasm under stress conditions; also involved in translation initiation.
    
 0.999
SPT15
TATA-binding protein (TBP); general transcription factor that interacts with other factors to form the preinitiation complex at promoters; essential for viability, highly conserved; yeast gene can complement mutations in human homolog TBP.
   
 0.999
RPB9
RNA polymerase II subunit B12.6; contacts DNA; mutations affect transcription start site selection and fidelity of transcription.
   
 0.999
TFG1
TFIIF (Transcription Factor II) largest subunit; involved in both transcription initiation and elongation of RNA polymerase II; homologous to human RAP74.
  
 0.999
RPB3
RNA polymerase II third largest subunit B44; part of central core; similar to prokaryotic alpha subunit.
   
 0.999
TFA1
Transcription initiation factor IIE subunit alpha; TFIIE large subunit; involved in recruitment of RNA polymerase II to the promoter, activation of TFIIH, and promoter opening.
   
 0.999
TFA2
TFIIE small subunit; involved in RNA polymerase II transcription initiation; Belongs to the TFIIE beta subunit family.
   
 0.999
RPB2
RNA polymerase II second largest subunit B150; part of central core; similar to bacterial beta subunit.
    
 0.999
