Citation | Journal: Cell / Year: 2016 Title: Structure of a Complete Mediator-RNA Polymerase II Pre-Initiation Complex. Authors: Philip J Robinson / Michael J Trnka / David A Bushnell / Ralph E Davis / Pierre-Jean Mattei / Alma L Burlingame / Roger D Kornberg / Abstract: A complete, 52-protein, 2.5 million dalton, Mediator-RNA polymerase II pre-initiation complex (Med-PIC) was assembled and analyzed by cryo-electron microscopy and by chemical cross-linking and mass ...A complete, 52-protein, 2.5 million dalton, Mediator-RNA polymerase II pre-initiation complex (Med-PIC) was assembled and analyzed by cryo-electron microscopy and by chemical cross-linking and mass spectrometry. The resulting complete Med-PIC structure reveals two components of functional significance, absent from previous structures, a protein kinase complex and the Mediator-activator interaction region. It thereby shows how the kinase and its target, the C-terminal domain of the polymerase, control Med-PIC interaction and transcription. | ||||||||||||||||||

Details | For cryo-EM, samples were chemically stabilized by fixation in glycerol gradients with increasing concentrations of glutaraldehyde (0-0.1%). Peak gradient fractions (~0.2 mg/mL) containing glutaraldhyde were quenched upon the addition of 50 mM Tris-HCl (pH 7.5) before flash-freezing and storage under liquid nitrogen. |
