    Phosphorylation of luminal region of the SUN-domain protein Mps3 promotes nuclear envelope localization during meiosis

    Hanumanthu BD Prasada Rao, Takeshi Sato ... Akira Shinohara
    Cytological analyses combined with in vitro liposome reconstitution reveal that yeast SUN domain protein, Mps3, shows meiosis-specific phosphorylation in the luminal region of the nuclear envelope during meiosis for chromosome motion and nuclear envelope remodelling.

    Shade-induced nuclear localization of PIF7 is regulated by phosphorylation and 14-3-3 proteins in Arabidopsis

    Xu Huang, Qian Zhang ... Lin Li
    A phosphorylation dependent translocation of PIF7 and involvement of 14-3-3 proteins reveal novel regulation mechanisms in shade signal transduction.

    Dynamic relocalization of replication origins by Fkh1 requires execution of DDK function and Cdc45 loading at origins

    Haiyang Zhang, Meghan V Petrie ... Oscar M Aparicio
    Establishment of replication-timing involves Fkh1-dependent recruitment and execution of DDK function in G1 phase resulting in dynamic relocalization of origins within the nucleus in anticipation of CDK-dependent origin activation.

    Molecular determinants of large cargo transport into the nucleus

    Giulia Paci, Tiantian Zheng ... Edward A Lemke
    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.

    Detection of TurboID fusion proteins by fluorescent streptavidin outcompetes antibody signals and visualises targets not accessible to antibodies

    Johanna Odenwald, Bernardo Gabiatti ... Susanne Kramer
    Proteins that are low abundant and/or poorly accessible to antibodies can be readily localised with fluorescent streptavidin, when expressed fused to a biotin ligase.

    The FAM104 proteins VCF1/2 promote the nuclear localization of p97/VCP

    Maria Körner, Susanne R Meyer ... Alexander Buchberger
    The previously uncharacterized, evolutionarily conserved FAM104 proteins VCF1/2 stimulate the nuclear import of p97/VCP, with their absence causing reduced nuclear p97/VCP levels, slow growth, and hypersensitivity to pharmacological inhibition of p97/VCP.

    IRAK2 directs stimulus-dependent nuclear export of inflammatory mRNAs

    Hao Zhou, Katarzyna Bulek ... Xiaoxia Li
    The stimulation of lipopolysaccharides induced nuclear localization of IRAK2 to facilitate nuclear export of a specific subset of inflammation-related messenger RNAs for translation in murine macrophages.

    Mitochondrial volume fraction and translation duration impact mitochondrial mRNA localization and protein synthesis

    Tatsuhisa Tsuboi, Matheus P Viana ... Brian M Zid
    Mitochondria can tune the protein synthesis of nuclear-encoded proteins through condition-dependent mRNA localization that is regulated by translation elongation and the geometric constraints of the cell.

    Cellular localization of the cell cycle inhibitor Cdkn1c controls growth arrest of adult skeletal muscle stem cells

    Despoina Mademtzoglou, Yoko Asakura ... Frederic Relaix
    Ablation of the Cdkn1c cell cycle inhibitor leads to defective muscle stem cell dynamics and myogenic potential, while progressive cytoplasmic to nuclear cellular localization of the Cdkn1c protein regulates growth arrest.

    Investigating molecular crowding within nuclear pores using polarization-PALM

    Guo Fu, Li-Chun Tu ... Siegfried M Musser
    The super-resolution fluorescence microscopy approach polarization PALM (p-PALM) reveals that macromolecular crowding and inhomogeneity within nuclear pores generate a structurally and dynamically complex permeability barrier.
