    Viral GPCR US28 can signal in response to chemokine agonists of nearly unlimited structural degeneracy

    Timothy F Miles et al.
    Numerous chemokine variants bearing no sequence resemblance elicit similar signaling behavior from the viral GPCR US28, suggesting a mechanism for receptor activation that accommodates extensive ligand degeneracy.

    Sensory Neurons: A new target for G protein signaling

    László Csanády
    G protein-coupled receptor stimulation inhibits TRPM3 channel activity through direct binding of the Gβγ subunit to the channel.

    CCR5 is a suppressor for cortical plasticity and hippocampal learning and memory

    Miou Zhou et al.
    Repression of the G protein-coupled chemokine receptor CCR5 enhances MAPK/CREB signaling, long-term potentiation, somatosensory cortical plasticity, and learning and memory, while CCR5 over-activation by viral proteins may contribute to HIV-associated cognitive deficits.

    Molecular basis of signaling specificity between GIRK channels and GPCRs

    Kouki K Touhara, Roderick MacKinnon
    A single kinetic step in the G protein activation cycle determines whether a G protein-coupled receptor activates G protein-gated K+ channels or not.

    Arabidopsis heterotrimeric G proteins regulate immunity by directly coupling to the FLS2 receptor

    Xiangxiu Liang et al.
    Heterotrimeric G proteins are coupled to and regulate plant receptor signaling, which allows optimum immune activation and enhances the production of reactive oxygen species.

    Mechano-dependent signaling by Latrophilin/CIRL quenches cAMP in proprioceptive neurons

    Nicole Scholz et al.
    Metabotropic mechanosensing occurs through an adhesion-type G protein-coupled receptor.

    The RFamide receptor DMSR-1 regulates stress-induced sleep in C. elegans

    Michael J Iannacone et al.
    During sickness, sleep is induced by neuropeptides, which contain an amidated arginine-phenylalanine motif, acting in a neuroendocrine fashion on a G-protein coupled receptor called DMSR-1.

    The Melanocortin Receptor Accessory Protein 2 promotes food intake through inhibition of the Prokineticin Receptor-1

    Anna L Chaly et al.
    A non-melanocortin G-protein coupled receptor is inhibited by the Melanocortin Receptor Accessory Protein 2 (MRAP2) to control food intake in mammals.

    Ric-8A, a G protein chaperone with nucleotide exchange activity induces long-range secondary structure changes in Gα

    Ravi Kant et al.
    Hydrogen-Deuterium exchange experiments show that Ric-8A induces similar dynamic changes in the structure of Gα as G protein-coupled receptors, yet protects a larger surface of the nucleotide-binding Ras domain.

    Olfactory receptor accessory proteins play crucial roles in receptor function and gene choice

    Ruchira Sharma et al.
    G protein-coupled odorant receptors regulate their own gene transcription based on their cell surface trafficking, which is facilitated by receptor transporting protein (RTP) family members.
