Here, we combine X-ray crystallography and cryo-electron microscopy (cryo-EM) to obtain a molecular model for basal Pol I initiation. The three-subunit CF binds upstream promoter DNA, docks to the Pol I-Rrn3 complex, and loads DNA into the expanded active center cleft of the polymerase. DNA unwinding between the Pol I protrusion and clamp domains enables cleft contraction, resulting in an active Pol I conformation and RNA synthesis. Comparison with the Pol II system suggests that promoter specificity relies on a distinct “bendability” and “meltability” of the promoter sequence that enables contacts between initiation factors, DNA, and polymerase."}],"citation":{"chicago":"Engel, Christoph, Tobias Gubbey, Simon Neyer, Sarah Sainsbury, Christiane Oberthuer, Carlo Baejen, Carrie Bernecky, and Patrick Cramer. “Structural Basis of RNA Polymerase I Transcription Initiation.” <i>Cell</i>.
