In eukaryotes, proteins must be transported in and out of the nucleus. This nucleocytoplasmic transport of proteins across the nuclear envelope must occur through the gateway of the NPC. The NPC is a large structure consisting of 456 constituent binding proteins called nucleoporins (Nups).1 Movement through the NPC is facilitated transport that relies on interaction with specific Nups. Importins and exportins are proteins that aid this facilitated transport by both binding to a specific cargo to be transported and interacting with specific Nups located in the central channel of the NPC.2 | In eukaryotes, proteins must be transported in and out of the nucleus.
