摘要
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 beta gamma subunits (G beta gamma), bind to the cytoplasmic regions of GIRK and modulate its activity. We established the backbone resonance assignments of H-2/C-13/N-15-labeled cytoplasmic regions of mouse GIRK1, which form a tetramer with a molecular weight of 96 K.
