STRINGSTRING
SUB1 protein (Saccharomyces cerevisiae) - STRING interaction network
"SUB1" - Transcriptional coactivator, facilitates elongation through factors that modify RNAP II in Saccharomyces cerevisiae
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

SUB1Transcriptional coactivator, facilitates elongation through factors that modify RNAP II; role in peroxide resistance involving Rad2p; role in the hyperosmotic stress response through polymerase recruitment at RNAP II and RNAP III genes; Plays a role in the release of TFIIB from the transcription complex during transcription initiation. Binds to TFIIB and specifically inhibits the formation of the TBP-TFIIB- promoter complexes (292 aa)    
Predicted Functional Partners:
PTA1
Subunit of holo-CPF, a multiprotein complex and functional homolog of mammalian CPSF, required for the cleavage and polyadenylation of mRNA and snoRNA 3’ ends; involved in pre-tRNA processing; binds to the phosphorylated CTD of RNAPII; Essential in pre-tRNA processing. Component of the cleavage and polyadenylation factor (CPF) complex, which plays a key role in polyadenylation-dependent pre-mRNA 3’-end formation and cooperates with cleavage factors including the CFIA complex and NAB4/CFIB. Component of the APT complex, which may be involved in polyadenylation-independent transcript 3’- [...] (785 aa)

SUA7
Transcription factor TFIIB, a general transcription factor required for transcription initiation and start site selection by RNA polymerase II; General factor that plays a major role in the activation of eukaryotic genes transcribed by RNA polymerase II (345 aa)
       
 
  0.896
NAB6
Putative RNA-binding protein; associates with mRNAs encoding cell wall proteins in high-throughput studies; deletion mutants display increased sensitivity to some cell wall disrupting agents; expression negatively regulated by cAMP; RNA-binding protein that associates with mRNAs encoding cell wall proteins (1134 aa)
       
 
  0.855
SPT5
Protein involved in regulating Pol I and Pol II transcription and pre-mRNA processing; forms a complex with Spt4p; contains a C-terminal repeat domain that is a target for phosphorylation by Sgv1p; The SPT4-SPT5 complex mediates both activation and inhibition of transcription elongation, and plays a role in pre- mRNA processing. This complex seems to be important for the stability of the RNA polymerase II elongation machinery on the chromatin template but not for the inherent ability of this machinery to translocate down the gene (1063 aa)
       
 
  0.846
SSU72
Transcription/RNA-processing factor that associates with TFIIB and cleavage/polyadenylation factor Pta1p; exhibits phosphatase activity on serine-5 of the RNA polymerase II C-terminal domain; affects start site selection in vivo; Component of the cleavage and polyadenylation factor (CPF) complex, which plays a key role in polyadenylation-dependent pre-mRNA 3’-end formation and cooperates with cleavage factors including the CFIA complex and NAB4/CFIB. Component of the APT complex, which may be involved in polyadenylation-independent transcript 3’-end formation. SSU72 is required for 3’- [...] (206 aa)
     
 
  0.821
SPT15
TATA-binding protein, general transcription factor that interacts with other factors to form the preinitiation complex at promoters, essential for viability; General transcription factor that functions at the core of the DNA-binding general transcription factor complex TFIID. Binding of TFIID to a promoter (with or without TATA element) is the initial step in preinitiation complex (PIC) formation. TFIID plays a key role in the regulation of gene expression by RNA polymerase II through different activities such as transcription activator interaction, core promoter recognition and select [...] (240 aa)
       
 
  0.819
RPB3
RNA polymerase II third largest subunit B44, part of central core; similar to prokaryotic alpha subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. Pol II is the central component of the basal RNA polymerase II transcription machinery. It is composed of mobile elements that move relative to each other. RPB3 is part of the core element with the central large cleft and the clamp element that moves to [...] (318 aa)
     
 
  0.792
FCP1
Carboxy-terminal domain (CTD) phosphatase, essential for dephosphorylation of the repeated C-terminal domain of the RNA polymerase II large subunit (Rpo21p); Processively dephosphorylates ’Ser-2’ and ’Ser-5’ of the heptad repeats YSPTSPS in the C-terminal domain of the largest RNA polymerase II subunit (RPB1). This promotes the activity of RNA polymerase II (732 aa)
       
 
  0.776
CWC21
Protein involved in RNA splicing by the spliceosome; component of a complex containing Cef1p; interacts genetically with ISY1 and BUD13; may bind RNA; has similarity to S. pombe Cwf21p; Involved in pre-mRNA splicing. May function at or prior to the first catalytic step of splicing at the catalytic center of the spliceosome, together with ISY1. May do so by stabilizing the catalytic center or the position of the RNA substrate (135 aa)

PAP1
Poly(A) polymerase, one of three factors required for mRNA 3’-end polyadenylation, forms multiprotein complex with polyadenylation factor I (PF I), also required for mRNA nuclear export; may also polyadenylate rRNAs; required for gene looping; Polymerase component of the cleavage and polyadenylation factor (CPF) complex, which plays a key role in polyadenylation- dependent pre-mRNA 3’-end formation and cooperates with cleavage factors including the CFIA complex and NAB4/CFIB (568 aa)
