Just as cities must carefully manage the flow of cars in and out of downtown, cells regulate the movement of molecules into and out of the nucleus.

The nuclear pore is a protein-lined channel in the nuclear envelope that regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is ...

Each nuclear pore complex (NPC) consists of more than 1,000 individual protein subunits with a total molecular mass of approximately 120 million daltons—the equivalent of more than 6.5 million water ...

In addition to exporting materials out of the nucleus, the protein, called Exportin-1 (also called Xpo1 or Crm1), seems to play a role in promoting gene transcription, the process that creates RNA ...
