Citation | Journal: Nat Struct Mol Biol / Year: 2020 Title: Structural basis for RNA polymerase III transcription repression by Maf1. Authors: Matthias K Vorländer / Florence Baudin / Robyn D Moir / René Wetzel / Wim J H Hagen / Ian M Willis / Christoph W Müller / Abstract: Maf1 is a conserved inhibitor of RNA polymerase III (Pol III) that influences phenotypes ranging from metabolic efficiency to lifespan. Here, we present a 3.3-Å-resolution cryo-EM structure of yeast ...Maf1 is a conserved inhibitor of RNA polymerase III (Pol III) that influences phenotypes ranging from metabolic efficiency to lifespan. Here, we present a 3.3-Å-resolution cryo-EM structure of yeast Maf1 bound to Pol III, establishing that Maf1 sequesters Pol III elements involved in transcription initiation and binds the mobile C34 winged helix 2 domain, sealing off the active site. The Maf1 binding site overlaps with that of TFIIIB in the preinitiation complex. | ||||||
