title: Nucleocytoplasmic transport: more than the usual suspects.
abstract: A paper in the August 9 issue of Cell describes a novel role for the nucleoporin Npap60/Nup50 as a soluble cofactor in importin-alpha:beta-mediated nuclear protein import. These findings add a new dimension of complexity to the current understanding of protein transport pathways.
