    A physical model describing the interaction of nuclear transport receptors with FG nucleoporin domain assemblies

    Raphael Zahn et al.
    A homopolymer-sphere model is shown to accurately reproduce the interactions that underpin selective gating of macromolecular transport into and out of the cell nucleus.

    Scaffold nucleoporins Nup188 and Nup192 share structural and functional properties with nuclear transport receptors

    Kasper R Andersen et al.
    Components of the nuclear pore complex share structural and functional features with soluble nuclear transport receptors, which suggests that there may be an evolutionary relationship between these two types of protein.

    Extensive cargo identification reveals distinct biological roles of the 12 importin pathways

    Makoto Kimura et al.
    Transport-based high-throughput identification of cargo proteins specific to all 12 human importin-β family nuclear import receptors revealed biological processes that the cargo cohorts of each receptor are involved in.

    Nup98 FG domains from diverse species spontaneously phase-separate into particles with nuclear pore-like permselectivity

    Hermann Broder Schmidt, Dirk Görlich
    How nuclear pore complexes establish their permeability barrier has been a long-standing question; now, this process can be reconstituted by a surprisingly simple and rapid self-assembly of Nup98 FG domains into selective FG phases.

    Golgi localized β1-adrenergic receptors stimulate Golgi PI4P hydrolysis by PLCε to regulate cardiac hypertrophy

    Craig A Nash et al.
    β-adrenergic receptors at the Golgi apparatus activate a local signaling pathway, not accessed by cell surface receptors, to drive cardiac hypertrophy and could represent a target for heart failure therapy.

    Importin-β modulates the permeability of the nuclear pore complex in a Ran-dependent manner

    Alan R Lowe et al.
    The Ran GTPase plays a role in defining the physical properties of the nuclear pore complex transport channel by remodeling the binding interactions of importin-β with the nucleoporin Nup153 at the nuclear face of the pore.

    Molecular determinants of large cargo transport into the nucleus

    Giulia Paci et al.
    Efficient nuclear transport of very large biomolecules, relevant for viral transport, scales non-linearly with size and its kinetics can be explained by a simple two-parameter energetic model.

    Wnt/PCP controls spreading of Wnt/β-catenin signals by cytonemes in vertebrates

    Benjamin Mattes et al.
    Wnt signaling regulates its effective signaling range by controlling Wnt ligand transport on signaling filopodia within vertebrate tissues.

    Spatial structure of disordered proteins dictates conductance and selectivity in nuclear pore complex mimics

    Adithya N Ananth et al.
    Biomimetic nanopores reveal that the sequence-dependent spatial distribution of intrinsically disordered proteins plays a crucial role in establishing the selective permeability barrier of the nuclear pore complex.
    1. Neuroscience

    Ring finger protein 10 is a novel synaptonuclear messenger encoding activation of NMDA receptors in hippocampus

    Margarita C Dinamarca et al.
    A protein called RNF10 relays messages from synapses to neuron cell nuclei, and is responsible for long-lasting modifications of dendritic spines as observed after activation of synaptic glutamate receptors.
