Function
KA120_YEAST Functions in nuclear protein import as nuclear transport receptor. Serves as receptor for nuclear localization signals (NLS) in cargo substrates. Thought to mediate docking of the importin/substrate complex to the nuclear pore complex (NPC) through binding to nucleoporin and the complex is subsequently translocated through the pore by an energy requiring, RAN-dependent mechanism. Required for nuclear import of Ho endonuclease and RFP1, and involved in rRNA-processing and assembly or export of 60S ribosomal subunits.[1] [2] [3] [4]
