靶點(diǎn)詳情

  • 功能：
    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.

    1. Chimeric transcript resulting from the fusion of RNF43 and SUPT4H1 was found to occur frequently in primary colorectal carcinoma. PMID: 27461012
    2. Knockdown of SUPT4H1, the human Spt4 ortholog, similarly decreased production of sense and antisense RNA foci, as well as dipeptide repeat proteins, in patient cells. PMID: 27516603
    3. crystal structure of hSpt4 in complex with the dimerization region of hSpt5 PMID: 19860741
    4. Upon induction of NF-kappaB, a subset of target genes is regulated differentially by either P-TEFb or DSIF.[P-TEFb, DSIF] PMID: 17502349
    5. These findings reveal a dynamic regulation of DSIF involving either E-box or NF-kappaB depending on the physiological circumstances. PMID: 17962196
    6. Spt4 was purified and characterized. PMID: 18373978
    7. 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. PMID: 19210550
    8. he Paf1 complex (Paf1C) and Tat-SF1, two factors implicated previously in elongation control, collaborate with DSIF to facilitate efficient elongation PMID: 19952111
