The nuclear pore complex.

The nuclear pore complex is the largest supramolecular complex that assembles in the eukaryotic cell. This structure is highly dynamic and must disassemble prior to mitosis and reassemble after the event. The directed movement of macromolecules into and out of the nucleus occurs through the nuclear pore complex, a potentially regulatory point for translocation. Using biochemical and genetic approaches, several nuclear pore complex proteins from yeast and vertebrates have been well characterized. Although very little is known about plant nuclear pore proteins, research is providing new information that indicates that plant nuclear pore complexes may have some unique features.
