    Epidermal Growth Factor Receptor neddylation is regulated by a desmosomal-COP9 (Constitutive Photomorphogenesis 9) signalosome complex

    Nicole Ann Najor et al.
    A protein interaction screen revealed desmosomes as a scaffold for the COP9 de-neddylating complex, to promote epidermal differentiation by governing the balance of Nedd8 and Ubiquitin modifications on Epidermal Growth Factor Receptor.

    A tension-adhesion feedback loop in plant epidermis

    Stéphane Verger et al.
    Tensile stress patterns in tissues are revealed by cell-cell adhesion defects; in turn, cell responses to supracellular tension require cell-cell adhesion.

    A cis-carotene derived apocarotenoid regulates etioplast and chloroplast development

    Christopher I Cazzonelli et al.
    Carotenoids are not just required as core components for plastid biogenesis, they can be cleaved into an apocarotenoid signal that regulates etioplast and chloroplast development during extended periods of darkness.
