Conformational changes at supramolecular interfaces are fundamentally coupled to binding activity, yet it remains a challenge to probe this relationship directly. Within the nuclear pore complex, this underlies how transport receptors known as karyopherins proceed through a tethered layer of

A series of five Phe-Gly dipeptidomimetics containing different amide bond replacements have been synthesized in a facile way from the readily available unsaturated ketoester 1, and their affinities for the di-/tripeptide transporters hPEPT1 (Caco-2 cells) and rPEPT2 (SKPT cells) were
Peptide ordering within nuclear pores in living cells.
Selective transport through the nuclear pore complex (NPC) requires nucleoporins containing natively unfolded phenylalanine-glycine (FG) domains. Several differing models for their dynamics within the pore have been proposed. We characterize the behavior of the FG nucleoporins in vivo using polarized fluorescence
beta-Catenin nuclear import has been found to be independent of classical nuclear localization signal (NLS) nuclear import factors. Here, we test the hypothesis that beta-catenin interacts directly with nuclear pore proteins to mediate its own transport. We show that beta-catenin
