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

NELF-BNegative elongation factor B; Essential component of the NELF complex, a complex that negatively regulates the elongation of transcription by RNA polymerase II. (594 aa)    
Predicted Functional Partners:
TH1
Negative elongation factor D; TH1 (TH1) encodes one of four subunits that constitutes the NELF complex. The NELF complex along with DSIF causes RNA polymerase II to pause 20 to 50 nucleotides downstream from the transcription start site of most and possibly all actively transcribed genes in a process commonly called promoter proximal pausing.

Nelf-E
Negative elongation factor E; Essential component of the NELF complex, a complex that negatively regulates the elongation of transcription by RNA polymerase II by RNA polymerase II. The NELF complex, which acts via an association with the DSIF complex, causes transcriptional pausing. Belongs to the RRM NELF-E family.

Spt5
Transcription elongation factor SPT5; Component of the DRB sensitivity-inducing factor complex (DSIF complex), which regulates transcription elongation by RNA polymerase II. DSIF enhances transcriptional pausing at sites proximal to the promoter, which may facilitate the assembly of an elongation competent RNA polymerase II complex. DSIF may also promote transcriptional elongation within coding regions. DSIF is required for the transcriptional induction of heat shock response genes and regulation of genes which control anterior-posterior patterning during embryonic development; Belongs [...]

Nelf-A
Negative elongation factor A; Essential component of the NELF complex, a complex that negatively regulates the elongation of transcription by RNA polymerase II. Has an essential role in postembryonic development.

Rpb3
RNA polymerase II 33kD subunit; DNA-directed 5'-3' RNA polymerase activity; RNA polymerase II activity; protein dimerization activity; DNA binding. It is involved in the biological process described with: transcription by RNA polymerase II; cellular response to heat.

spt4
Transcription elongation factor SPT4; Component of the DRB sensitivity-inducing factor complex (DSIF complex), which regulates transcription elongation by RNA polymerase II. DSIF enhances transcriptional pausing at sites proximal to the promoter, which may facilitate the assembly of an elongation competent RNA polymerase II complex. DSIF may also promote transcriptional elongation within coding regions. DSIF is required for the transcriptional induction of heat shock response genes and regulation of genes which control anterior-posterior patterning during embryonic development (By simi [...]

Rpb5
Rpb5, isoform A; DNA-directed 5'-3' RNA polymerase activity; RNA polymerase III activity; RNA polymerase II activity; RNA polymerase I activity; DNA binding. It is involved in the biological process described with: tRNA transcription by RNA polymerase III; transcription by RNA polymerase II; transcription by RNA polymerase I.

RpII15
DNA-directed RNA polymerase II subunit RPB9; 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. RPB9 is part of the upper jaw surrounding the central large cleft and thought to grab the incoming DNA template (By similarity); Belongs to the archaeal RpoM [...]

Cdk9
Positive transcription elongation factor b small subunit; Cyclin-dependent kinase 9 (Cdk9) encodes a cyclin dependent kinase that along with the product of CycT forms the positive transcription elongation factor, which is involved in RNA polymerase II elongation control.

RpII215
DNA-directed RNA polymerase II subunit RPB1; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Largest and catalytic component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. Forms the polymerase active center together with the second largest subunit. 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. RPB1 is part of the core element with the central large cl [...]
