    Cooperative regulation by G proteins and Na+ of neuronal GIRK2 K+ channels

    Weiwei Wang, Kouki K Touhara ... Roderick MacKinnon
    Determining how GIRK2 activity depends on the concentration of Gβγ subunits in lipid membranes at different Na+ concentrations has allowed the Gβγ concentration generated during GABAB activation in neurons to be estimated.

    Estradiol elicits distinct firing patterns in arcuate nucleus kisspeptin neurons of females through altering ion channel conductances

    Jian Qiu, Margaritis Voliotis ... Martin J Kelly
    Kiss1ARH neurons transition from synchronous to burst firing under preovulatory levels of E2, causing a shift from peptidergic to glutamatergic transmission that drives the GnRH surge through enhanced glutamate neurotransmission.

    How IGF-1 activates its receptor

    Jennifer M Kavran, Jacqueline M McCabe ... Daniel J Leahy
    Ligand binding to the ectodomain of the insulin-like growth factor receptor destabilises an autoinhibitory inter-subunit interaction, which allows the transmembrane domains to associate and the intracellular regions to autophosphorylate.

    G protein βγ subunits inhibit TRPM3 ion channels in sensory neurons

    Talisia Quallo, Omar Alkhatib ... Stuart Bevan
    TRPM3 inhibition is identified as a novel mechanism for G-protein βγ subunit signalling.
