(Submitter supplied) The human Negative Elongation Factor (NELF) is a four-subunit protein complex that inhibits the movement of RNA polymerase II (RNAPII) at an early elongation stage in vitro. NELF-mediated stalling of RNAPII also attenuates transcription of a number of inducible genes in human cells. To obtain a genome-wide understanding of human NELF-mediated transcriptional regulation in vivo, we carried out an exon-array study in T47D breast cancer cells with transient siRNA knockdown of individual NELF subunits. more...

(Submitter supplied) RNAPII pausing/termination shortly after initiation is a hallmark of gene regulation. However, the molecular mechanisms involved are still to be uncovered. Here, we show that NELF interacts with Integrator complex subunits (INTScom) forming a stable complex with RNPII and Spt5. The interaction between NELF and INTScom subunits is RNA and DNA independent. Using both HIV-1 promoter and genome wide analyses, we demonstrate that Integrator subunits specifically control NELF-mediated RNAPII pause/release at coding genes. more...

(Submitter supplied) Jurkat T-cells were latently infected with a defective HIV provirus carrying a GFP reporer gene. The cells were superinfected with a lentiviral vector expressing shRNA to NELF-E. The impact of NELF-depletion on RNAP II distribution on cellular genes and the HIV provirus was measured by ChIP-Seq. Data sets contained between 45 and 56 million mapped reads

(Submitter supplied) We examineD the genomic oppucpany and role of negative elongation factor A (NelfA) aka, Wolf-Hirschhorn syndrome candidate 2 (Whsc2), a critical component of the negative elongation complex in hearts undergoing pressure-overload induced cardiac hypertrophy. Alignment of high resolution genome wide occupancy data of NelfA, RNA Pol II, TFIIB and H3k9ac (datasets for pol II, TFIIB and H3kac submitted before) from control and hypertrophied hearts reveal that NelfA associates with all active gene promoters. more...

(Submitter supplied) Deletion of the flap loop in the Rp2 subunit of human RNAPII did not alter the ability of human RNAPII to initiate transcription or elongate the initiated transcripts in vivo and in vitro, and was also dispensable for elongation factor-mediated enhancement and inhibition of transcript elongation in vitro. ChIP:chip of wild-type and flap deletion human RNAPII revealed that the mutant RNAPII was not defective for promoter binding, initiation and elongation in vivo.

(Submitter supplied) Transcriptional regulation in eukaryotes commonly occurs at promoter-proximal regions wherein transcriptionally engaged RNA Polymerase II (Pol II) pauses before proceeding towards productive elongation. The roles of chromatin in this process remains poorly understood. Here, we demonstrate that the histone deacetylase SIRT6 regulates transcription elongation by binding to Pol II and anchoring the Negative ELongation Factor NELF, thereby preventing the release of Pol II towards elongation. more...

(Submitter supplied) RNA polymerase II (Pol II) is generally paused at promoter-proximal regions in most metazoans, and based on in vitro studies, this function has been attributed to the negative elongation factor (NELF). Here, we show that upon rapid depletion of NELF, Pol II fails to be released into gene bodies, stopping instead around the +1 nucleosomal dyad-associated region. The transition to the 2nd pause region is independent of positive transcription elongation factor P-TEFb. more...

(Submitter supplied) Epigenetic regulation of chromatin plays a critical role in controlling embryonic stem (ES) cell self-renewal and pluripotency. However, the roles of histone demethylases and activating histone modifications such as trimethylated histone 3 lysine 4 (H3K4me3) in transcriptional events such as RNA polymerase II (RNAPII) elongation and alternative splicing are largely unknown. In this study, we show that KDM5B, which demethylates H3K4me3, plays an integral role in regulating RNAPII occupancy, transcriptional initiation and elongation, and alternative splicing events in ES cells. more...
