    Quantitative analysis of mammalian GIRK2 channel regulation by G proteins, the signaling lipid PIP2 and Na+ in a reconstituted system

    Weiwei Wang et al.
    The G protein subunits Gβγ and the signaling lipid PIP2 are simultaneously needed to activate the potassium ion channel GIRK2 to control the voltage across a lipid bilayer, while sodium ions modulate these molecules' effects.
