      • NAADP: A Universal Ca2+ Trigger

        NAADP elicits an initial release of calcium, which is subsequently amplified through the action of other calcium messengers.

      • Thrombin Targets Notch Signaling

        Cleavage of the Notch ligand Jagged1 by thrombin appears to promote nonclassical release of fibroblast growth factor 1 by inhibiting Notch signaling.

      • PRMT Versus Akt for FOXO

        FOXO transcriptional activity is promoted by arginine methylation, which blocks phosphorylation by Akt.

      • TRPM7 and T Cell Development

        A cation channel that conducts both Ca2+ and Mg2+ is unexpectedly required for normal mouse development, specifically for proper maturation of the thymus and T cells.

      • Transporter in Action

        The structure of a membrane transporter in an open state suggests that inward- and outward-facing cavities reciprocally open and close coordinated by two transmembrane segments.

      • Of Glia and Senses

        Non-neural glial cells are required for the normal operation of the main sensory organ of a nematode, influencing neuronal shape and function, as well as behavior.
