Backbone resonance assignments for the cytoplasmic regions of G protein-activated inwardly rectifying potassium channel 1 (GIRK1).
G protein-activated inwardly rectifying potassium channel (GIRK) plays crucial roles in regulating heart rate and neuronal excitability in eukaryotic cells. A variety of ligands, including heterotrimeric G protein betagamma subunits (G betagamma), bind to the cytoplasmic regions of GIRK and modulate its activity. We established the backbone resonance assignments of (2)H/(13)C/(15)N-labeled cytoplasmic regions of mouse GIRK1, which form a tetramer with a molecular weight of 96 K.
