Nuclear pores are protein channels that span the nuclear envelope of eukaryotic cells. These pores act as gatekeepers, allowing the selective movement of molecules in and out of the nucleus. Synonyms for nuclear pore include nuclear pore complex, nuclear pore apparatus, and nuclear pore structure. Other terms used to describe these structures include nuclear basket, nuclear pore membrane, and nuclear transport machinery. The importance of nuclear pores cannot be overstated, as they control the flow of genetic material and macromolecules between the nucleus and the cytoplasm. Understanding the function and structure of nuclear pores is crucial for advancing our knowledge of cell biology and gene expression.
