    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.

    Cooperative cobinding of synthetic and natural ligands to the nuclear receptor PPARγ

    Jinsai Shang, Richard Brust ... Douglas J Kojetin
    Synthetic PPARγ ligands push and cobind with natural endogenous ligands, instead of compete and displace, which synergistically affects the structure and function of PPARγ.

    Piezo’s membrane footprint and its contribution to mechanosensitivity

    Christoph A Haselwandter, Roderick MacKinnon
    Membrane mechanics predict that the ion channel Piezo recruits the surrounding membrane to amplify its sensitivity to changes in membrane tension, with greatest sensitivity in the low-tension regime.
