    Breakage of the oligomeric CaMKII hub by the regulatory segment of the kinase

    Deepti Karandur et al.
    Activation and autophosphorylation of CaMKII releases the regulatory segment, which can then bind to and destabilize the hub assembly by trapping large fluctuations in the hub architecture.

    The genetic factors of bilaterian evolution

    Peter Heger et al.
    Advanced orthology clustering of bilaterian and non-bilaterian sequences identifies 157 bilaterian-specific genes which are linked to key morphological features of this animal group.

    Pattern regulation in a regenerating jellyfish

    Chiara Sinigaglia et al.
    Clytia jellyfish regenerate body shape and organs through a mechanically driven process that coordinates tissue remodeling, localized proliferation, and precursor migration and promotes Wnt signaling at a muscle-based landmark.

    TMEM79/MATTRIN defines a pathway for Frizzled regulation and is required for Xenopus embryogenesis

    Maorong Chen et al.
    TMEM79 targets frizzled receptor for degradation through inhibiting USP8 and is required for Xenopus embryogenesis.

    Hedgehog signaling is required for endomesodermal patterning and germ cell development in the sea anemone Nematostella vectensis

    Cheng-Yi Chen et al.
    The dependence of Nematostella germ cell specification on zygotic Hedgehog pathway activity supports the hypothesis that the eumetazoan common ancestor segregated its germline by inductive signals rather than maternal determinants.

    Par protein localization during the early development of Mnemiopsis leidyi suggests different modes of epithelial organization in the metazoa

    Miguel Salinas-Saavedra, Mark Q Martindale
    Even though the ctenophore Mnemiopsis leidyi develops polarized epithelial tissues, polarization is not mediated by the conserved mechanisms polarizing bilaterian and cnidarian epithelial cells.

    Global alignment and assessment of TRP channel transmembrane domain structures to explore functional mechanisms

    Katherine E Huffer et al.
    Structure-based alignment of TRP channels enables comparison of structural changes, ion permeation pathways and ligand-binding sites and reveals over-representation of structures that represent non-conducting states.

    Wnt/β-catenin signaling is an evolutionarily conserved determinant of chordate dorsal organizer

    Iryna Kozmikova, Zbynek Kozmik
    Wnt/beta-catenin signaling is essential for the specification of dorsal cell fate in amphioxus, suggesting a common evolutionary origin for the formation of the dorsal organizer in chordates.

    A molecular filter for the cnidarian stinging response

    Keiko Weir et al.
    Cnidarian stinging cells use a specialized voltage-gated calcium channel to integrate distinct sensory signals and selectively trigger a predatory response.

    A unicellular relative of animals generates a layer of polarized cells by actomyosin-dependent cellularization

    Omaya Dudin et al.
    Cellularization in Sphaeroforma arctica generates a self-organized structure that morphologically resembles an epithelium, and is associated with tightly regulated expression of cell adhesion pathways.
