Four G protein gated inwardly-rectifying potassium (GIRK) channel subunits have been identified in mammals: GIRK1, GIRK2, GIRK3, and GIRK4. Thgirke GIRK subunits come together to form GIRK ion channels.

G-protein-gated inwardgirkly rectifying K + (GIRK) channels play a key role in maintaining resting membrane potential, cell excitability and inhibitory neurotransmission.

G protein-coupled inwardly recgirktifying potassium (GIRK) channels can be activated or inhibited by different classes of receptors, suggesting a role for G proteins in determining signaling specificity.
