    Spatially compartmentalized phase regulation of a Ca2+-cAMP-PKA oscillatory circuit

    Brian Tenner et al.
    Nanodomain clustering of cAMP effectors represents a novel mechanism of cAMP compartmentation within an oscillatory signaling circuit.

    Sir2 phosphorylation through cAMP-PKA and CK2 signaling inhibits the lifespan extension activity of Sir2 in yeast

    Woo Kyu Kang et al.
    The deacetylase Sir2 fine-tunes transcription of PMA1 and other aging related genes in a cAMP-PKA and CK2 signaling dependent manner.

    Chronic social isolation reduces 5-HT neuronal activity via upregulated SK3 calcium-activated potassium channels

    Derya Sargin et al.
    Serotonin neurons in chronically isolated mice become less responsive to excitatory stimulation, but inhibiting a distinctive calcium-activated potassium channel can restore both neuronal activity and behavior.

    Endoplasmic reticulum-associated SKN-1A/Nrf1 mediates a cytoplasmic unfolded protein response and promotes longevity

    Nicolas J Lehrbach, Gary Ruvkun
    SKN-1A/Nrf1 promotes healthy aging by activating protein degradation in response to accumulation of misfolded proteins.

    Photosynthetic sea slugs induce protective changes to the light reactions of the chloroplasts they steal from algae

    Vesa Havurinne, Esa Tyystjärvi
    Slug chloroplasts avoid damage to photosynthesis by maintaining an oxidized electron transfer chain with the help of oxygen-sensitive electron acceptors.

    The human SKA complex drives the metaphase-anaphase cell cycle transition by recruiting protein phosphatase 1 to kinetochores

    Sushama Sivakumar et al.
    Microtubule binding by the Spindle and Kinetochore Associated (Ska) complex concentrates protein phosphatase 1 at metaphase kinetochores to overcome the spindle checkpoint thus driving anaphase onset and mitotic exit.

    Existence and functions of a kisspeptin neuropeptide signaling system in a non-chordate deuterostome species

    Tianming Wang et al.
    Identification and functional characterization of the first non-chordate kisspeptin neuropeptide system in the sea cucumber indicates the ancient origin of the intracellular signaling and physiological functions of this molecular system.

    IL17 factors are early regulators in the gut epithelium during inflammatory response to Vibrio in the sea urchin larva

    Katherine M Buckley et al.
    Expression of two highly regulated subfamilies of the complex multigene family encoding IL-17 cytokines in the purple sea urchin are sequentially activated in a larval gut-associated inflammation model and modulate downstream gene expression in the gut epithelium.

    Endothelial PKA activity regulates angiogenesis by limiting autophagy through phosphorylation of ATG16L1

    Xiaocheng Zhao et al.
    The cAMP-dependent protein kinase A controls the switch from actively sprouting new blood vessel formation to vessel quiescence by reducing endothelial autophagy through phosphorylation-mediated destabilisation of ATG16L1.

    Glucose intake hampers PKA-regulated HSP90 chaperone activity

    Yu-Chen Chen et al.
    Food overconsumption impairs cellular protein folding through a novel aging-related signaling pathway.
