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

    Zhengjian Zhang et al.
    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.

    Single-molecule tracking in live cells reveals distinct target-search strategies of transcription factors in the nucleus

    Ignacio Izeddin et al.
    While the transcription factor c-Myc explores the space in the nucleus in an unrestricted manner, the elongation factor P-TEFb's sampling of the nucleus is constrained to a complex domain with fractal characteristics.

    Sustained TNF-α stimulation leads to transcriptional memory that greatly enhances signal sensitivity and robustness

    Zuodong Zhao et al.
    Sustained TNF-α induction consolidates transcriptional memory for faster, stronger, and more sensitive subsequent induction in an active DNA demethylation-dependent manner for memory genes including CALCB, a therapeutic target for migraine.

    Conservation of transcription factor binding specificities across 600 million years of bilateria evolution

    Kazuhiro R Nitta et al.
    Drosophila has almost all transcription factor binding specificities available to humans; and human transcription factors with divergent specificities operate in cell types that are not found in fruit flies.

    Nascent-Seq reveals novel features of mouse circadian transcriptional regulation

    Jerome S Menet et al.
    Genome-wide measurements on mouse liver cells show that transcription, and a particular key transcription factor, have a smaller than expected influence on the mouse circadian system.

    Set1/COMPASS and Mediator are repurposed to promote epigenetic transcriptional memory

    Agustina D'Urso et al.
    Epigenetic transcriptional memory employs a novel regulatory strategy to create a heritable poised state by remodeling and repurposing complexes involved in active transcription.

    Co-transcriptional R-loops are the main cause of estrogen-induced DNA damage

    Caroline Townsend Stork et al.
    The transcriptional response elicited by the hormone estrogen leads to DNA double-strand breaks by promoting R-loop formation in breast cancer cells.

    Identification of the transcription factor ZEB1 as a central component of the adipogenic gene regulatory network

    Carine Gubelmann et al.
    A large-scale transcription factor screen reveals over twenty novel adipogenic regulators: most notably ZEB1, which exerts essential transcriptional control of fat cell differentiation.

    Structural basis of transcription inhibition by the DNA mimic protein Ocr of bacteriophage T7

    Fuzhou Ye et al.
    DNA mimicry Ocr protein, a well-studied T7 phage protein that inhibits host restriction enzymes, can also inhibit host transcription through competing with sigma factors in binding to RNA polymerase.

    A combination of transcription factors mediates inducible interchromosomal contacts

    Seungsoo Kim et al.
    A pooled mutational scanning approach for 3D chromosome conformation reveals how multiple transcription factors can jointly specify condition-specific genome conformations.
