(Submitter supplied) Biochemical studies have established that the four-subunit negative elongation factor (NELF) complex mediates RNA polymerase II (Pol II) pausing at promoter proximal regions. Genetic ablation of individual NELF subunits destabilizes the entire NELF complex and causes lethality of cultured cells, leading to the prevailing concept that NELF-mediated Pol II pausing is essential for cell survival. Using separation-of-function mutations, we show here that NELFB’s effects on cell proliferation can be uncoupled from its function in Pol II pausing. more...

(Submitter supplied) The master transcriptional regulator T cell factor 1 (TCF1) is required for the anti-tumor functions of memory and stem-like CD8+ T cells. However, how TCF1 partners with other transcription factors to orchestrate the gene activation program critical for anti-tumor immunity remains poorly understood. Here we show that negative elongation factor B (NELFB), an RNA polymerase II pausing factor, cooperates with TCF1 in T cell responses to cancer. more...

(Submitter supplied) Many mammalian genes are occupied by paused RNA polymerase II (pol II) at promoter-proximal regions on both sides of transcription start sites (TSSs). However, the consequences of pol II pausing on gene expression and cell biology are not fully understood. Here we report that genetic ablation of the b subunit of mouse negative elongation factor (Nelf-b), a key pol II-pausing factor, results in slower progression at multiple cell cycle stages and increased apoptosis. more...

(Submitter supplied) Many factors control the elongation phase of transcription by RNA polymerase II (Pol II), a process that plays an essential role in regulating gene expression. We utilized cells expressing degradation tagged subunits of NELFB, PAF1 and RTF1 to probe the effects of depletion of the factors on nascent transcripts using PRO-Seq and on chromatin architecture using DFF-ChIP. Although NELF is involved in promoter proximal pausing, depletion of NELFB had only a minimal effect on the level of paused transcripts and almost no effect on control of productive elongation. more...

(Submitter supplied) Cdk9 is an essential transcriptional kinase that is conserved across distant eukaryotes, but we previously found that acute inhibition of Cdk9 causes different transcriptional phenotypes in NELF-containing higher eukaryotes (like mammals and Drosophila) vs. the NELF-lacking fission yeast S. pombe. NELF is known to participate in promoter-proximal pausing of RNA Polymerase II, and using NELF-depleted Drosophila cells,  we find that this NELF-mediated pause is necessary to prevent gene body entry by Pol II in the absence of Cdk9. 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) Control of gene expression is one of the most complex yet continuous physiological processes impacting cellular homeostasis. RNA polymerase II (Pol II) transcription is tightly regulated at promoter-proximal regions by intricate dynamic processes including Pol II pausing, release into elongation, and premature termination. Here, we identify PTEN interacting with the Pol II transcription machinery and dephosphorylating Pol II C-terminal domain in vitro. more...

(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) The ERK pathway induces cell proliferation in response to growth factor stimulation. Although ERK controls various transcription factors in the nucleus, gene regulation mechanisms underlying the rapid IEG inductions were not fully elucidated. Here we report that ERK phosphorylates an unique novel substrate. We found that ERK facilitates rapid transcription of IEGs through the phosphorylation of the substrate.

(Submitter supplied) The current work describes molecular mechanism used by the Negative elongation complex (NELF) to control the Pol II pause at genes whose transcription is induced by 20-hydroxyecdysone (20E). According to our data NELF complex is recruited to the promoters and enhancers of 20E-dependent genes. Its presence at the regulatory sites of 20E-dependent genes correlates with the described interaction of its NELF-A subunit with EcR receptor. more...
