Authors: Julia L Daiß / Michael Pilsl / Kristina Straub / Andrea Bleckmann / Mona Höcherl / Florian B Heiss / Guillermo Abascal-Palacios / Ewan P Ramsay / Katarina Tlučková / Jean-Clement Mars / ...Authors: Julia L Daiß / Michael Pilsl / Kristina Straub / Andrea Bleckmann / Mona Höcherl / Florian B Heiss / Guillermo Abascal-Palacios / Ewan P Ramsay / Katarina Tlučková / Jean-Clement Mars / Torben Fürtges / Astrid Bruckmann / Till Rudack / Carrie Bernecky / Valérie Lamour / Konstantin Panov / Alessandro Vannini / Tom Moss / Christoph Engel / Abstract: Transcription of the ribosomal RNA precursor by RNA polymerase (Pol) I is a major determinant of cellular growth, and dysregulation is observed in many cancer types. Here, we present the purification ...Transcription of the ribosomal RNA precursor by RNA polymerase (Pol) I is a major determinant of cellular growth, and dysregulation is observed in many cancer types. Here, we present the purification of human Pol I from cells carrying a genomic GFP fusion on the largest subunit allowing the structural and functional analysis of the enzyme across species. In contrast to yeast, human Pol I carries a single-subunit stalk, and in vitro transcription indicates a reduced proofreading activity. Determination of the human Pol I cryo-EM reconstruction in a close-to-native state rationalizes the effects of disease-associated mutations and uncovers an additional domain that is built into the sequence of Pol I subunit RPA1. This "dock II" domain resembles a truncated HMG box incapable of DNA binding which may serve as a downstream transcription factor-binding platform in metazoans. Biochemical analysis, in situ modelling, and ChIP data indicate that Topoisomerase 2a can be recruited to Pol I via the domain and cooperates with the HMG box domain-containing factor UBF. These adaptations of the metazoan Pol I transcription system may allow efficient release of positive DNA supercoils accumulating downstream of the transcription bubble. | |||||||||
