New insights have been provided into how nuclear pores are constructed in the nuclear envelope. Nuclear pores regulate the exchange of macromolecules between the interior of the nucleus, where genetic information is stored, and the cytoplasm, where these blueprints are used to produce many different cellular building blocks. More than a million macromolecules are transported through the 3,000 – 4,000 nuclear pores in a human nucleus every minute. This exchange is a vital function and transport errors are associated with cancer, aging and autoimmune diseases.
