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.
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.
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.
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.
