Nuclear 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 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...
متن کاملThe nuclear pore complex and nuclear transport.
Internal membrane bound structures sequester all genetic material in eukaryotic cells. The most prominent of these structures is the nucleus, which is bounded by a double membrane termed the nuclear envelope (NE). Though this NE separates the nucleoplasm and genetic material within the nucleus from the surrounding cytoplasm, it is studded throughout with portals called nuclear pore complexes (N...
متن کاملPiecing together nuclear pore complex assembly during interphase
All nucleocytoplasmic traffic of macromolecules occurs through nuclear pore complexes (NPCs), which function as stents in the nuclear envelope to keep nuclear pores open but gated. Three studies in this issue (Flemming, D., P. Sarges, P. Stelter, A. Hellwig, B. Böttcher, and E. Hurt. 2009. J. Cell Biol. 185:387-395; Makio, T., L.H. Stanton, C.-C. Lin, D.S. Goldfarb, K. Weis, and R.W. Wozniak. 2...
