    Architecture of TAF11/TAF13/TBP complex suggests novel regulation properties of general transcription factor TFIID

    Kapil Gupta, Aleksandra A Watson ... Imre Berger
    Integrative structural biology reveals a novel complex comprising the TATA-box-binding protein, TBP, and two subunits, TAF11 and TAF13, of General Transcription Factor TFIID, suggesting a new regulatory state in TFIID function in RNA polymerase II transcription initiation.

    A specific E3 ligase/deubiquitinase pair modulates TBP protein levels during muscle differentiation

    Li Li, Silvia Sanchez Martinez ... Robert Tjian
    Proteasome-mediated degradation of the TATA-box binding protein (TBP) during terminal differentiation is regulated by the E3 ligase Huwe1 and the deubiquitinase USP10.

    Chemical perturbation of an intrinsically disordered region of TFIID distinguishes two modes of transcription initiation

    Zhengjian Zhang, Zarko Boskovic ... Robert Tjian
    An inorganic tin oxochloride cluster specifically binds to an intrinsically disordered, histidine-rich, low complexity protein region and arrests de novo transcription initiation without affecting reinitiation.

    Crystal structure of the full Swi2/Snf2 remodeler Mot1 in the resting state

    Agata Butryn, Stephan Woike ... Karl-Peter Hopfner
    The structure of the entire Mot1 Swi2/Snf2 protein uncovers an unexpected auto-inhibited resting state activated by substrate binding, and suggests a DNA pulling mechanism of TBP displacement.

    Translation in amino-acid-poor environments is limited by tRNAGln charging

    Natalya N Pavlova, Bryan King ... Craig B Thompson
    Amino acid limitation triggers preferential uncharging of glutamine-specific tRNAs and depletes polyglutamine tract-containing proteins from mammalian cells, revealing a potential role for polyglutamine tracts as sensors of glutamine sufficiency.

    Non-canonical TAF complexes regulate active promoters in human embryonic stem cells

    Glenn A Maston, Lihua Julie Zhu ... Michael R Green
    The transcription machinery used to regulate gene expression and self-renewal in human embryonic stem cells is different from that found in other cells.

    Mitotically heritable, RNA polymerase II-independent H3K4 dimethylation stimulates INO1 transcriptional memory

    Bethany Sump, Donna G Brickner ... Jason H Brickner
    During epigenetic transcriptional memory in budding yeast, histone H3 lysine 4 dimethylation - dependent on Nup1000 and independent of RNA polymerase II - regulates binding of a critical transcription factor and, once established, is mitotically heritable for at least four cell divisions.

    Two roles for the yeast transcription coactivator SAGA and a set of genes redundantly regulated by TFIID and SAGA

    Rafal Donczew, Linda Warfield ... Steven Hahn
    The transcription coactivators SAGA and TFIID have redundant function at a subset of yeast genes while SAGA also contributes to transcription of all genes through regulation of chromatin modifications.

    Genetic dissection of the RNA polymerase II transcription cycle

    Shao-Pei Chou, Adriana K Alexander ... Charles G Danko
    Natural genetic variation reveals how DNA sequence impacts core transcriptional processes of initiation, pause, and termination.
