    Symmetric exchange of multi-protein building blocks between stationary focal adhesions and the cytosol

    Jan-Erik Hoffmann, Yessica Fermin ... Eli Zamir
    In the cytosol, the proteins constituting cell-matrix adhesion sites form multi-protein building blocks which enter and leave these sites unaltered, thereby contributing to their rapid and correct self-assembly.

    The cell adhesion molecule Sdk1 shapes assembly of a retinal circuit that detects localized edges

    Pierre-Luc Rochon, Catherine Theriault ... Arjun Krishnaswamy
    A novel retinal ganglion cell requires a cell adhesion molecule to grow its dendrites, collect synaptic inputs, and become selective to edges placed in its receptive field.

    Dynamic fibronectin assembly and remodeling by leader neural crest cells prevents jamming in collective cell migration

    William Duncan Martinson, Rebecca McLennan ... Philip K Maini
    Data-driven mathematical modeling suggests that leading neural crest cells in a moving stream can robustly communicate with trailing cells by remodeling their extracellular matrix, thereby enabling long-distance collective migration.

    Histone supply regulates S phase timing and cell cycle progression

    Ufuk Günesdogan, Herbert Jäckle, Alf Herzig
    Controlling cell cycle progression in a developing embryo directly depends on de novo histone supply and a specialized surveillance mechanism for nucleosome assembly.

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

    Jordina Guillén-Boixet, Víctor Buzon ... Raúl Méndez
    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.

    Assembly and positioning of actomyosin rings by contractility and planar cell polarity

    Ivonne M Sehring, Pierre Recho ... Di Jiang
    Contractility wins over the polarity pathway in a tug-of-war to position a cytokinesis-like actomyosin ring at the equator of notochord cells.

    Kidney organoids recapitulate human basement membrane assembly in health and disease

    Mychel RPT Morais, Pinyuan Tian ... Rachel Lennon
    Kidney organoids are a high-fidelity system for investigating basement membrane regulation in development and disease.

    A ribosome assembly stress response regulates transcription to maintain proteome homeostasis

    Benjamin Albert, Isabelle C Kos-Braun ... David Shore
    Ribosome assembly is monitored to promote proteostatis through a system whereby unassembled ribosomal proteins lead to activation of heat shock factor 1 and inactivation of the RP gene activator Ifh1.

    Mechanisms of PDZ domain scaffold assembly illuminated by use of supported cell membrane sheets

    Simon Erlendsson, Thor Seneca Thorsen ... Kenneth Lindegaard Madsen
    Investigations of binding of the scaffold protein PICK1 to transmembrane proteins in their native membrane environment demonstrate potent but slow dynamics and reveal distinct binding modes supporting different biological functions.

    Large protein complex interfaces have evolved to promote cotranslational assembly

    Mihaly Badonyi, Joseph A Marsh
    Analysis of protein interfaces suggests cotranslational assembly can be an adaptive process, likely serving to minimise non-specific interactions with other proteins in the cell.
