    Recruitment of mRNAs to P granules by condensation with intrinsically-disordered proteins

    Chih-Yung S Lee, Andrea Putnam ... Geraldine Seydoux
    The intrinsically-disordered protein MEG-3 recruits mRNAs to P granules by forming gel-like condensates with ribosome-depleted mRNAs.

    Protein-based condensation mechanisms drive the assembly of RNA-rich P granules

    Helen Schmidt, Andrea Putnam ... Geraldine Seydoux
    P granule assembly depends in part on protein-protein interactions that drive condensation independent of RNA.

    Regulation of RNA granule dynamics by phosphorylation of serine-rich, intrinsically disordered proteins in C. elegans

    Jennifer T Wang, Jarrett Smith ... Geraldine Seydoux

    Novel LOTUS-domain proteins are organizational hubs that recruit C. elegans Vasa to germ granules

    Patricia Giselle Cipriani, Olivia Bay ... Kristin C Gunsalus
    Two novel LOTUS-domain proteins are core germ granule components that directly recruit Caenorhabditis elegans Vasa, regulate germ granule size and localization, and provide an organizational framework for ribonucleoprotein complexes.

    Promiscuous interactions and protein disaggregases determine the material state of stress-inducible RNP granules

    Sonja Kroschwald, Shovamayee Maharana ... Simon Alberti
    A comparison in yeast and human cells reveals a remarkable variability in the properties of RNP granules and highlights a key role for protein disaggregation machines in regulating RNP granule assembly.

    Proximity labeling identifies LOTUS domain proteins that promote the formation of perinuclear germ granules in C. elegans

    Ian F Price, Hannah L Hertz ... Wen Tang
    A proximity labeling approach defines germ granule proteome in Caenorhabditis elegans, and identifies LOTUS domain proteins as key regulators of germ granule assembly.

    Host casein kinase 1-mediated phosphorylation modulates phase separation of a rhabdovirus phosphoprotein and virus infection

    Xiao-Dong Fang, Qiang Gao ... Xian-Bing Wang
    Liquid-liquid phase separation of a rhabovirus phosphoprotein initiates viral factory formation of barley yellow striate mosaic virus, a plant negative-sense RNA virus, and host casein kinase 1-mediated phosphorylation inhibits phase separation and virus infection.

    A tudor domain protein, SIMR-1, promotes siRNA production at piRNA-targeted mRNAs in C. elegans

    Kevin I Manage, Alicia K Rogers ... Carolyn Marie Phillips
    SIMR-1 acts downstream of the piRNA pathway to promote siRNA amplification by the Mutator complex and localizes to perinuclear foci distinct from Mutator foci, P granules and Z granules.

    Pak1 kinase controls cell shape through ribonucleoprotein granules

    Joseph O Magliozzi, James B Moseley
    A newly discovered substrate of Pak1 kinase reveals novel mechanisms that control cell shape through regulated assembly of ribonucleoprotein granules.
