FG-nucleoporin component of the nuclear pore complex central core; direct role in nucleocytoplasmic transport and maintenance of the NPC permeability barrier; role in gene tethering at the nuclear periphery; short linear motifs connect Mlp1p and the Y-complex via Nup85p to facilitate nuclear basket docking onto the core of the NPC; Cdc5p-mediated phosphorylation leads to detachment and reattachment of the basket during meiosis; both NUP1 and NUP60 are human NUP153 homologs
