A Model of Interaction among Components Involved in Nucleocytoplasmic Transport
It is not clear whether the drawn interactions occur simultaneously. NLS, karyophilic protein with a nuclear localization sequence; α, karyopherin-α/importin-α; β, karyopherin-β/importin-β; RanGDP, Ran/TC4 in its GDP-bound form; pp15, nuclear import factor pp15; nucleoporin with Ran-binding domain (Ran-BD), FXFG repeat sequences (FXFG), and an NPC-binding domain (NPC-BD).
