The molecular architecture of the plant nuclear pore complex

The nuclear pore complex: from molecular architecture to functional dynamics.

Toward dissecting the molecular composition and architecture of the nuclear pore complex (NPC), over the past 18 months novel nucleoporins and NPC subcomplexes were identified and characterized. The three-dimensional structure of isolated yeast NPCs was determined by electron cryomicroscopy. New specimen preparation and labeling protocols localized a number of nucleoporins and NPC subcomplexes ...

Molecular Architecture of the Transport Channel of the Nuclear Pore Complex

The nuclear pore complex encloses a central channel for nucleocytoplasmic transport, which is thought to consist of three nucleoporins, Nup54, Nup58, and Nup62. However, the structure and composition of the channel are elusive. We determined the crystal structures of the interacting domains between these nucleoporins and pieced together the molecular architecture of the mammalian transport chan...

Molecular Architecture of the Major Membrane Ring Component of the Nuclear Pore Complex.

The membrane ring that equatorially circumscribes the nuclear pore complex (NPC) in the perinuclear lumen of the nuclear envelope is composed largely of Pom152 in yeast and its ortholog Nup210 (or Gp210) in vertebrates. Here, we have used a combination of negative-stain electron microscopy, nuclear magnetic resonance, and small-angle X-ray scattering methods to determine an integrative structur...

The 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...
