Integrated Structural Analysis of the Human Nuclear Pore Complex Scaffold
The nuclear pore complex (NPC) is a fundamental component of all eukaryotic cells that facilitates nucleocytoplasmic exchange of macromolecules. It is assembled from multiple copies of about 30 nucleoporins. Due to its size and complex composition, determining the structure of the NPC is an enormous challenge, and the overall architecture of the NPC scaffold remains elusive. In this study, we h...
متن کاملNuclear pore complex biogenesis.
Nuclear pore complexes (NPCs) are the sole mediators of transport between the nucleus and the cytoplasm. NPCs have a life cycle: they assemble, disassemble, turnover, and age. The molecular mechanisms governing these different vital steps are beginning to emerge, suggesting key roles for the core structural scaffold of the NPC and auxiliary factors in the assembly of this large macromolecular c...
متن کاملStructural plasticity of the cardiac nuclear pore complex in response to regulators of nuclear import.
Communication between the cytoplasm and nucleoplasm of cardiac cells occurs by molecular transport through nuclear pores. In lower eukaryotes, nuclear transport requires the maintenance of cellular energetics and ion homeostasis. Although heart muscle is particularly sensitive to metabolic stress, the regulation of nuclear transport through nuclear pores in cardiomyocytes has not yet been chara...
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...
متن کاملThe nuclear pore complex.
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...
