These findings are consistent with a central role of Spt5 in maintenance of TFIID-promoter association and promoter escape to support rapid transcriptional induction and re-initiation of inflammatory-response genes.
The mobile C-terminal region of DSIF is located near exiting RNA, where it can recruit factors for RNA processing.
OGA is physically associated with the known RNA polymerase II (pol II) pausing/elongation factors SPT5 and TRIM28-KAP1-TIF1beta, and a purified OGA-SPT5-TIF1beta complex has elongation properties.
A transcription-independent effect of tumor necrosis factor alpha on RNA splicing, mediated by Spt5.
SPT5 contributes to the up-regulation of hTERT expression and colonic tumor development.
Data indicate that the Plus3 domain of the Rtf1 subunit mediates Paf1C recruitment to genes by binding a repeating domain within the phosphorylated elongation factor Spt5.
DSIF Is Selectively Required for mRNA Splicing and Export of NF-kappaB Target Genes.
RNA polymerase II elongation repression is critically dependent on the C-terminus of Spt5
crystal structure of hSpt4 in complex with the dimerization region of hSpt5
phosphorylated by P-TEFb kinase during HIV-1 transcription in Tat/TAR dependent manner
hSpt5 function in transcription regulation and mRNA capping is essential for a subset of cellular and viral genes and may not be required for global gene expression.
evolutionarily conserved repetitive heptapeptide motif (consensus = G-S-R/Q-T-P) in the C-terminal region of hSpt5, like the C-terminal domain of RNA Pol II, is highly phosphorylated by P-TEFb
Upon induction of NF-kappaB, a subset of target genes is regulated differentially by either P-TEFb or DSIF.[P-TEFb, DSIF]
These findings reveal a dynamic regulation of DSIF involving either E-box or NF-kappaB depending on the physiological circumstances.
These results suggest that one of the functions of Spt5 is to suppress senescence and apoptosis, and that this function is exerted through its association with Spt4 and Pol II.
he Paf1 complex (Paf1C) and Tat-SF1, two factors implicated previously in elongation control, collaborate with DSIF to facilitate efficient elongation

Spt5 as a dual regulator of transcription elongation in vivo; a small but diverse set of target genes critically dependent on Spt5 during development.
Mutation in the protein-protein interaction domain (REPO domain) of Pho interferes with the dynamics of its interaction with Spt5. The transcriptional kinetics of the heat shock response is negatively affected by a mutation in the REPO domain of Pho
KOW5 is involved in promoter-proximal pausing through contact with the nascent RNA
Spt5 interacts both physically and genetically with the Polycomb Group (PcG) protein Pleiohomeotic (Pho)
We show that SPT5 interacts directly with MSL1 in vitro and is required downstream of MSL complex recruitment, providing the first mechanistic data corroborating the elongation model of dosage compensation.
Spt5 acts both positively and negatively on transcription in vivo during heat shock induction.
Component of the DRB sensitivity-inducing factor complex (DSIF complex), which regulates mRNA processing and transcription elongation by RNA polymerase II. DSIF positively regulates mRNA capping by stimulating the mRNA guanylyltransferase activity of RNGTT/CAP1A. DSIF also acts cooperatively with the negative elongation factor complex (NELF complex) to enhance transcriptional pausing at sites proximal to the promoter. Transcriptional pausing may facilitate the assembly of an elongation competent RNA polymerase II complex. DSIF and NELF promote pausing by inhibition of the transcription elongation factor TFIIS/S-II. TFIIS/S-II binds to RNA polymerase II at transcription pause sites and stimulates the weak intrinsic nuclease activity of the enzyme. Cleavage of blocked transcripts by RNA polymerase II promotes the resumption of transcription from the new 3' terminus and may allow repeated attempts at transcription through natural pause sites. DSIF can also positively regulate transcriptional elongation and is required for the efficient activation of transcriptional elongation by the HIV- 1 nuclear transcriptional activator, Tat. DSIF acts to suppress transcriptional pausing in transcripts derived from the HIV-1 LTR and blocks premature release of HIV-1 transcripts at terminator sequences.
