    Spatial patterning of P granules by RNA-induced phase separation of the intrinsically-disordered protein MEG-3

    Jarrett Smith et al.
    A competition for RNA drives the localized assembly of RNA granules in the C. elegans embryo.

    CPEB4 is regulated during cell cycle by ERK2/Cdk1-mediated phosphorylation and its assembly into liquid-like droplets

    Jordina Guillén-Boixet et al.
    CPEB4's switch from translational repressor to activator is regulated during cell cycle by hyperphosphorylation of its intrinsically disordered domain, which controls its phase-separation into RNA-containing liquid-like droplets.

    Multivalency regulates activity in an intrinsically disordered transcription factor

    Sarah Clark et al.
    Binding of multiple LC8 copies to the intrinsically disordered region of the transcription factor ASCIZ exemplifies a new and potentially widespread molecular mechanism for negative feedback regulation.

    A dynamic charge-charge interaction modulates PP2A:B56 substrate recruitment

    Xinru Wang et al.
    A novel dynamic charge-charge interaction between B56 and a subset of PP2A-B56 substrates is essential for substrate specificity, dephosphorylation and, for KIF4A, binding condensin I.

    Nucleophosmin integrates within the nucleolus via multi-modal interactions with proteins displaying R-rich linear motifs and rRNA

    Diana M Mitrea et al.
    Nucleolar protein localization involves the phase separation within the nucleolar matrix via three types of multivalent features: acidic tracts, nucleic acid binding domains and arginine-rich low complexity sequences.

    A widely employed germ cell marker is an ancient disordered protein with reproductive functions in diverse eukaryotes

    Michelle A Carmell et al.
    GCNA proteins comprise a previously unnoticed family of proteins that has been enriched in cells carrying a heritable genome since the invention of sexual reproduction in eukaryotes, and has had reproductive function for at least 600 million years.

    The acidic domain of the endothelial membrane protein GPIHBP1 stabilizes lipoprotein lipase activity by preventing unfolding of its catalytic domain

    Simon Mysling et al.
    Intravascular triglyceride hydrolysis by lipoprotein lipase is crucial for delivering lipid nutrients to vital tissues, such as the heart, skeletal muscle, and adipose tissue.

    An order-to-disorder structural switch activates the FoxM1 transcription factor

    Aimee H Marceau et al.
    Structural and biochemical analysis reveals that two intrinsically disordered domains of the transcription factor FoxM1 co-fold to form an autoinhibited conformation, which is disrupted by a specific activating phosphorylation event.

    Acidic C-terminal domains autoregulate the RNA chaperone Hfq

    Andrew Santiago-Frangos et al.
    Modeling and biophysics show that the unstructured acidic tail of the Sm protein Hfq mimics nucleic acid to auto inhibit its chaperone activity, preventing Hfq from being sequestered by inauthentic substrates and providing insight into the evolution of Hfq's chaperone function among bacterial genera.

    The AFF4 scaffold binds human P-TEFb adjacent to HIV Tat

    Ursula Schulze-Gahmen et al.
    Structure-function analysis of the super elongation complex formed when HIV replicates inside cells reveals that the HIV-1 Tat protein binds to a cleft between P-TEFb, an enzyme that is involved in normal transcription, and AFF4, a protein that is used to build the super elongation complex
