   2.7.7.6 | CK2 |
is associated with Pol I, the initiation-competent subclass of Pol I, CK2 phosphorylates a number of proteins involved in Pol I transcription and pre-rRNA processing, including UBF, TIF-IA, SL1/TIF-IB, topoisomerase IIa, nucleolin, and nucleophosmin, overview |

| 2.7.7.6 | Ctk1 |
the kinase is required for the stability of the scaffold, but Ctk1 kinase activity is not required for the dissociation of basal transcription factors |

| 2.7.7.6 | glutamate |
glutamate remodels the sigma38 transcription complex for activation. Accumulation of the simple signaling molecule glutamate can reprogram RNA polymerase in vitro without the need for specific protein receptors. During osmotic activation, glutamate appears to act as a Hofmeister series osmolyte to facilitate promoter escape. Escape is accompanied by a remodeling of the key interaction between the sigma38 stress protein and the beta-flap of the bacterial core RNA polymerase. This activation event contrasts with the established mechanism of inhibition in which glutamate, by virtue of its electrostatic properties, helps to inhibit binding to ribosomal promoters after osmotic shock |

| 2.7.7.6 | histone-like nucleoid structuring protein |
i.e. H-NS, H-NS stimulates transcription from the F3 fragment, it can facilitate specific DNA-binding by RNA polymerase in AT-rich gene regulatory regions. Correct positioning of RNA polymerase at PehxCABD requires H-NS. Footprint of RNA polymerase (s70 RC461-FeBABE) interactions with -10 elements in the ehxCABD regulatory region in the presence of H-NS, overview |

intermittent hypoxia, a major pathological factor in the development of neural deficits associated with sleep-disordered breathing, regulates RNA polymerase II in hippocampus and prefrontal cortex. Chronic intermittent hypoxia, but not sustained hypoxia, stimulates hydroxylation of Pro1465 in large subunit of RNA polymerase II and phosphorylation of Ser5 of Rpb1, specifically in the CA1 region of the hippocampus and in the prefrontal cortex but not in other regions of the brain, requiring the von Hippel-Lindau tumor suppressor. Mice exposed to chronic IH demonstrated cognitive deficits related to dysfunction in those brain regions |

Pol III initiates and reinitiates transcription in the absence or presence of transcription factors, during the first transcription cycle transcription factors IIIB and IIIC mainly contribute to the selectivity and not to the rate of Pol III association to the template, while their stable association with the promoter in subsequent cycles strongly contributes to the high rate of transcription reinitiation by Pol III |
