The Nuclear Pore Complex (NPC) is a 50 MDa macromolecular assembly solely responsible for the transport of macromolecules across the nuclear membrane within the eukaryotic cell. The core structure of the NPC (shown as a wire-mesh) is made up of two outer rings, two inner rings and a membrane ring. A hybrid method approach was used to determine the detailed architecture of the NPC combining structural data from crystallography, small-angle x-ray scattering, normal mode analysis, molecular dynamics simulation and electron microscopy as well as information from functional and biochemical studies.
