    Light-inducible control of protein subcellular localization holds great promise for synthetic biology applications and insights into basic cell biology. Here the authors develop a genetically-encoded light-inducible nuclear export system and apply it to a synthetic repressor and p53 transcriptional activity.

    While ERK signalling can produce switch-like cell behaviour, phosphorylation of ERK increases linearly with extracellular signals. Here, the authors solve this seeming contradiction by showing that nuclear translocation of ERK behaves in a switch-like manner and is controlled by ERK activity.

    Measuring single-cell mRNA dynamics is critical to understand gene expression. Here, using RNA Spinach technique to detect very low abundant mRNAs, Guet et al. report an analysis of the osmotic shock response in live yeast by localizing induced transcription factors, target gene loci and corresponding transcripts.

    Endocytosis typically directs proteins on a recycling route back to the plasma membrane, transport to the Golgi apparatus or delivery to the lysosome. Here Chaumet et al.describe a population of vesicles that can fuse directly with the outer nuclear membrane and deliver cargo into the nuclear envelope, where it can be translocated into the nucleoplasm.

    Nuclear pore complexes (NPCs) are large macromolecular assemblies that mediate the exchange of molecules between the nucleus and cytoplasm. Here the authors present a ∼20 Å cryo-EM structure of the X. laevisNPC in different states of transport to propose a model for the architecture of the NPC’s molecular gate within its central channel.

    Eukaryotic ribosomal proteins contain nuclear localization signals (NLSs) that their bacterial counterparts lack. Here the authors compare homologous proteins from bacterial and eukaryotic ribosomes to show how NLSs could emerge in the course of evolution, and use this knowledge to identify novel NLSs.

    Biogenesis of the 80S ribosome involves more than 200 pre-ribosomal factors, which ensure the sequential assembly of ribosomal proteins and RNAs. Here the authors show that the nuclear transport adaptor Syo1 shields the 5S RNP-docking site on RpL11 before incorporation into the pre-60S through molecular mimicry.

    The extracellular signal-regulated kinase 1/2 (ERK1/2) cascade is involved in the induction and maintenance of cancers. Here the authors design an ERK-derived peptide that blocks ERK nuclear import, thus proposing a novel approach to treat tumours with mutational activation of the ERK pathway.

    Heat shock induces proteotoxic stress, and the cellular response is mediated by heat-shock factor 1 (HSF1). Here, Tan et al.show that following heat shock, mitochondrial SSBP1 translocates to the nucleus and binds HSF1 to enhance the expression of chaperones and support the maintenance of mitochondrial function.

    Retroviruses such as HIV integrate into the host genome as an essential step prior to their replication. Here Lelek et al. identify nuclear pore complex proteins that are essential for HIV nuclear import and productive integration, and show that the intranuclear protein Tpr influences integration into transcriptionally active chromatin.

    TFIID is an essential transcription factor complex that controls the expression of most protein-coding genes in eukaryotes. Here the authors identify and characterize a complex containing TAF2, TAF8 and TAF10, which assembles in the cytoplasm before integration into the nuclear holo–TFIID complex.

    Nuclear import of transcriptional regulators and export of mRNA are essential steps for the manufacture of proteins in the cytoplasm. Here, Rajakylä et al.link these two activities by showing that the mRNA export factor Ddx19 promotes the nuclear import of the transcriptional coactivator MKL1.

    The human Holliday junction resolvase GEN1 functions during anaphase to eliminate recombination intermediates that block proper chromosome segregation. Here, the authors demonstrate that GEN1 activity is regulated independently of its phosphorylation status and relies on its active exclusion from the nucleus.

    Messenger RNAs and their associated proteins are transported from the nucleus through highly selective nuclear pore complexes. Using ultrahigh resolution single-molecule imaging, the authors visualise the path taken by each messenger RNA as it negotiates the pore’s selectivity filter.

    Zonal occludens and claudin form tight junctions near the apical surface of cells and are important in polarized epithelia. In this study, the translational regulatory sequence-specific RNA binding protein CPEB is shown to be required for the correct localization of zona occluden 1 mRNA in mammary epithelial cells.

    The pre-mRNA splicing and TREX mRNA export machineries are found in nuclear speckle domains. Diaset al. microinject CMV-DNA constructs into cells and find that transcripts containing functional splice sites accumulate in nuclear speckles and that the TREX complex is required to release the mRNA once processed.
