The Nuclear Pore-Associated TREX-2 Complex Employs Mediator to Regulate Gene Expression
Nuclear pore complexes (NPCs) influence gene expression besides their established function in nuclear transport. The TREX-2 complex localizes to the NPC basket and affects gene-NPC interactions, transcription, and mRNA export. How TREX-2 regulates the gene expression machinery is unknown. Here, we show that TREX-2 interacts with the Mediator complex, an essential regulator of RNA Polymerase (Po...
متن کاملThe human TREX-2 complex is stably associated with the nuclear pore basket.
In eukaryotes, mRNA export involves many evolutionarily conserved factors that carry the nascent transcript to the nuclear pore complex (NPC). The THO/TREX complex couples transcription to mRNA export and recruits the mRNA export receptor NXF1 for the transport of messenger ribonucleoprotein particles (mRNP) to the NPC. The transcription and export complex 2 (TREX-2) was suggested to interact w...
متن کاملThe nuclear pore complex
M OLECULAR trafficking between the nucleus and the cytoplasm of interphase eukaryotic cells occurs via the nuclear pore complexes (NPCs), 1 organelles with a roughly cylindrical shape (~,120 um in diameter and ~70-um high) that are embedded in the double-membraned nuclear envelope (NE). The NPC allows passive diffusion of ions and small molecules through an aqueous channel with a physical diame...

Over the past years, significant progress has been made both in the analysis of the structural and molecular organization of the nuclear pore complex (NPC) and the mechanism of nuclear transport. In this minireview, I will focus on some of the recent developments in this field. Structural studies employing high resolution EM have revealed a detailed view of the three-dimensional organization of...
متن کاملAdding complexity to the nuclear pore complex
Nuclear pore complexes (NPCs) span the inner and outer membranes of the nuclear envelope and mediate transport between the nucleus and cytoplasm. In recent years, however, NPCs and the proteins that form them, known as nucleoporins, have also been linked to nuclear events including chromatin organization and gene expression , and to physiological processes such as differentiation and aging. Two...
