Single molecule DNA unzipping reveals a novel model for the regulation of transcription factors and nucleosome positioning via nucleosome remodeling in yeast.
The myopathic transcription factor DUX4 induces discordant dysregulation of transcript and protein levels, demonstrating a key role for post-transcriptional gene regulation in facioscapulohumeral muscular dystrophy.
Analysis of the atypical tryptophan biosynthetic operon of Chlamydia trachomatis revealed the simultaneous regulation of transcriptional initiation and termination by an iron-dependent repressor, expanding known regulatory mechanisms of this pathway.
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.
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.
PHF13 interacts with transcriptional complexes containing RNA polymerase II to recruit/stabilize them at H3K4me2/3 containing active or bivalent promoters.
The maternally provided histone demethylase LSD1/KDM1A has an instrumental role at the beginning of life, shaping the histone methylation landscape and the transcriptional repertoire of the early mouse embryo.
Contrary to the generally accepted model, condensin maintains proper gene expression by promoting the accurate segregation of chromosomes and the partitioning of the RNA-exosome throughout mitosis, instead of directly regulating transcription.
The ion channel accessory subunit KChIP2 has a transcriptional role that provides regulation over miRNA targets, driving the adverse remodeling of key ion channels during cardiac stress and leading to the development of arrhythmia.
