Functions as a component of the nuclear pore complex (NPC) (PubMed:11684705). Involved in poly(A)+ RNA transport (PubMed:11684705). Part of the nuclear pore complex (NPC) (PubMed:11684705). Forms part of the NUP160 subcomplex in the nuclear pore which is composed of nup160, nup133, nup107, Nup96 and sec13p (PubMed:11684705). Nup85 may also be present (PubMed:11684705). This complex plays a role in RNA export and in tethering Nup98 and nup153 to the nucleus (PubMed:11684705). The order of the peptides shown is unknown.
