Which factors play a role in promoter proximal pausing of RNA polymerase II?
['Among the factors we describe are the pausing factors--NELF (negative elongation factor) and DSIF (DRB sensitivity-inducing factor)', 'BMP target gene expression requires the pause-inducing negative elongation factor (NELF) complex', 'NA polymerase II (Pol II) and the pausing complex, NELF and DSIF, are detected near the transcription start site (TSS) of many active and silent genes', 'pausing complex NELF/DSIF', 'knockdown of the pause-inducing factor NELF leads to broadly attenuated immune gene activation', 'pausing factors NELF and DSIF', 'pausing factors NELF and DSIF', 'pausing factor DSIF (DRB sensitivity-inducing factor)', '(NELF) and 5,6-dichloro-1-beta-D-ribofuranosylbenzimidazole sensitivity-inducing factor (DSIF) are involved in pausing RNA Polymerase II (Pol II) in the promoter-proximal region', 'Pausing and resumption of the elongation of transcripts is under the control of transcription elongation factors. Three of them, P-TEFb, DSIF, and NELF have been well characterized ', 'NELF-mediated stalling of RNAPII ', 'At several eukaryotic promoters, DSIF, together with NELF (negative elongation factor), leads to promoter-proximal pausing of RNA polymerase II', 'negative transcription elongation factor NELF', '(DSIF), is involved in regulating the processivity of RNA polymerase II. DSIF plays also a role in transcriptional activation, and in concert with the negative elongation factor NELF causes promoter proximal pausing of RNA polymerase II', 'NELF causes Pol II to pause in the promoter-proximal region', '(DSIF) regulates RNA polymerase II (RNAPII) processivity by promoting, in concert with negative elongation factor (NELF), promoter-proximal pausing of RNAPI', '(DSIF) and negative elongation factor (NELF) negatively regulate transcription elongation by RNA polymerase II (RNAPII) in vitro.', 'pausing caused by NELF ', 'ELF and DSIF collaborate to inhibit elongation by RNA polymerase IIa', 'The presence of DSIF reduced pausing,']
