FACT complex subunit spt16; Component of the FACT complex, a general chromatin factor that acts to reorganize nucleosomes. The FACT complex is involved in multiple processes that require DNA as a template such as mRNA elongation, DNA replication and DNA repair. During transcription elongation the FACT complex acts as a histone chaperone that both destabilizes and restores nucleosomal structure. It facilitates the passage of RNA polymerase II and transcription by promoting the dissociation of one histone H2A-H2B dimer from the nucleosome, then subsequently promotes the reestablishment o [...]

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.

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 [...]

IP02321p; Single-stranded DNA binding; DNA-directed 5'-3' RNA polymerase activity; protein binding; single-stranded RNA binding; translation initiation factor binding. It is involved in the biological process described with: positive regulation of translational initiation; positive regulation of nuclear-transcribed mRNA poly(A) tail shortening; transcription initiation from RNA polymerase II promoter; nuclear-transcribed mRNA catabolic process, exonucleolytic; transcription by RNA polymerase II.

Hyrax, isoform A; Hyrax (hyx) encodes a protein recruited by signaling pathway specific transcriptional regulators such as the products of arm and ci and is important for the output of Wingless and Hedgehog pathways.

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.

FACT complex subunit Ssrp1; Component of the FACT complex, a general chromatin factor that acts to reorganize nucleosomes. The FACT complex is involved in multiple processes that require DNA as a template such as mRNA elongation, DNA replication and DNA repair. During transcription elongation the FACT complex acts as a histone chaperone that both destabilizes and restores nucleosomal structure.

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.

DNA-directed RNA polymerase II subunit RPB2; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Second largest component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. Proposed to contribute to the polymerase catalytic activity and forms the polymerase active center together with the 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. RPB2 is [...]
