CELL BIOLOGY: ON NUCLEAR EXPORTATION

CELL BIOLOGY: ON NUCLEAR EXPORTATION: "Nuclear transport is mediated by short sequence elements in cargo molecules: cargo carrying a nuclear localization sequence (NLS) is imported, whereas a nuclear export sequence (NES) is used for export. These sequence elements are recognized by transport factors, collectively termed karyopherins (also referred to as importins, exportins or transportins), which ferry the cargo."
