摘要
G protein-coupled inwardly rectifying potassium channels (GIRK/Kir3) are important elements in controlling cellular excitability. In recent years, tremendous progress has been made toward understanding various components involved in channel activation, modulation, and signaling specificity. In this review, we summarize these recent findings and attempt to put them in context with recently available structural data.
