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.
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.
The discontinuous speed of transcription enables riboswitch molecules to adopt meta-stable structures in response to the presence of their cognate ligand, thereby gene-regulation by means of structure induced transcription termination can occur.
