Graphical Abstract

Transport forces: To move molecules across the nuclear envelope they have to overcome the selective barrier of the nuclear pore which is formed by nucleoporins (nups) with FG repeats. The molecules are chaperoned by shuttling receptors that interact with FG nups thereby passing the barrier using an unresolved mechanism. This process is explored by single-molecule force spectroscopy (see picture).
