    A Myt1 family transcription factor defines neuronal fate by repressing non-neuronal genes

    Joo Lee, Caitlin A Taylor ... Kang Shen
    First comprehensive genetic analysis of a Myt1 family protein reveals that neurogenesis requires direct repression of non-neuronal identities by the Myt1 family protein through MuvB co-repressor complex.

    Dissociation rate compensation mechanism for budding yeast pioneer transcription factors

    Benjamin T Donovan, Hengye Chen ... Michael G Poirier
    The budding yeast transcription factors Reb1 and Cbf1 function as pioneer factors by slowly dissociating from nucleosomes, allowing them to target and unwrap nucleosomes efficiently to regulate transcription.

    Genome-wide dynamics of Pol II elongation and its interplay with promoter proximal pausing, chromatin, and exons

    Iris Jonkers, Hojoong Kwak, John T Lis
    The elongation rate of RNA Polymerase II varies greatly between and along genes, as this enzyme accelerates from stable pausing to rapid elongation within genes, and is influenced by CG-content, exons and chromatin.

    Evidence for a common evolutionary rate in metazoan transcriptional networks

    Anne-Ruxandra Carvunis, Tina Wang ... Trey Ideker
    Transcriptional regulation evolves at indistinguishable rates in mammals, birds and insect lineages despite large differences in underlying rates of sequence evolution.

    A switch in transcription and cell fate governs the onset of an epigenetically-deregulated tumor in Drosophila

    Joana Torres, Remo Monti ... Renato Paro
    A previously unknown oncogenic feature of an embryonic transcription factor was uncovered from transcriptomic analysis of tumors that lack functional Polycomb silencing.

    Quantitative dissection of transcription in development yields evidence for transcription-factor-driven chromatin accessibility

    Elizabeth Eck, Jonathan Liu ... Hernan G Garcia
    Confronting different models of chromatin accessibility with temporally resolved transcription profiles favors a scenario where transcription factors actively, rather than passively, drive chromatin from the inaccessible to the accessible state.

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

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

    Transcription elongation is finely tuned by dozens of regulatory factors

    Mary Couvillion, Kevin M Harlen ... L Stirling Churchman
    NET-seq analysis of 41 S. cerevisiae transcription regulatory factors uncovers their differential and opposing effects on Pol II transcription elongation and antisense transcription, revealing that wild-type transcription is balanced by the joint impact of many regulators.

    Fluctuations of the transcription factor ATML1 generate the pattern of giant cells in the Arabidopsis sepal

    Heather M Meyer, José Teles ... Adrienne H K Roeder
    Fluctuations of a transcription factor that coincide with the G2 phase of the cell cycle pattern two interspersed cell fates in a multicellular system.

    Combinatorial chromatin dynamics foster accurate cardiopharyngeal fate choices

    Claudia Racioppi, Keira A Wiechecki, Lionel Christiaen
    ATAC-seq, CRISPR/Cas9 mutagenesis, reporter and gene expression assays revealed dynamic chromatin accessibility profiles governing differential gene expression during heart vs. pharyngeal muscle fate choices in the powerful chordate model Ciona.
