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

Pbp49PSEA-binding protein 49kD (Pbp49) encodes a protein that functions as one of three subunits of the small nuclear RNA (snRNA) activating protein complex, which binds as a complex to a proximal sequence element A (PSEA) to activate transcription of snRNA genes. (377 aa)    
Predicted Functional Partners:
Pbp95
PSEA-binding protein 95kD (Pbp95) encodes a protein that functions as one of three subunits of the small nuclear RNA (snRNA) activating protein complex, which binds as a complex to a proximal sequence element A (PSEA) to activate transcription of snRNA genes.

TfIIB
Transcription factor IIB (TfIIB) encodes a basal transcription factor that binds to the TATA box-binding protein. It is required for the initiation of transcription by RNA polymerase II.

CG42516
LD18062p1; It is involved in the biological process described with: transcription by RNA polymerase III.
 
    
 0.869
TfIIA-S
Transcription initiation factor IIA subunit 2; TFIIA is a component of the transcription machinery of RNA polymerase II and plays an important role in transcriptional activation. TFIIA in a complex with TBP mediates transcriptional activity. Part of a rhi-dependent transcription machinery that enables the generation of piRNA precursors from heterochromatin while maintaining the suppression of transposon-encoded promoters and enhancers. Forms a complex with Moonshiner/CG12721 and Trf2 which recruit transcriptional machinery to heterochromatin to initiate the bidirectional transcription [...]

Tbp
TATA binding protein (Tbp) encodes a basal transcription factor required at most RNA Pol I and Pol II-transcribed genes. Traditionally thought to be recruited only to TATA box containing promoters, recent work shows that promoters with very weak TATA box consensus sequences also recruit the product of Tbp as a part of the multisubunit TFIID basal transcription factor or via the SAGA histone acetyltransferase complex.
   
 0.823
TfIIA-L
Transcription factor IIA L (TfIIA-L) encodes a precursor protein that, after proteolysis, produces the two larger subunits of TFIIA. TFIIA is a general transcription factor that is required for initiation by RNA polymerase II and is a component of the pre-initiation complex.
   
  0.810
Trf
TBP-related factor (Trf) is ubiquitiously expressed but upregulated in the central nervous system and the gonads of developing Drosophila. The majority of the product of Trf substitutes for the product of Tbp in Pol III transcription in complex with the product of Brf. The rest of the product of Trf initiates transcription of a small subset of PolII-transcribed genes regulating fly fertility and nervous system function.

TfIIFalpha
General transcription factor IIF subunit 1; TFIIF is a general transcription initiation factor that binds to RNA polymerase II and helps to recruit it to the initiation complex in collaboration with TFIIB. It promotes transcription elongation. Belongs to the TFIIF alpha subunit family.
   
  0.782
TfIIFbeta
General transcription factor IIF subunit 2; TFIIF is a general transcription initiation factor that binds to RNA polymerase II and helps to recruit it to the initiation complex in collaboration with TFIIB. It promotes transcription elongation. This subunit shows ATP-dependent DNA-helicase activity (By similarity).
