The G protein-coupled inwardly rectifying potassium channels (GIRKs) are a family of lipid-gated inward-rectifier potassium ion channels which are activated (opened) by the signaling lipid PIP2 and a signal transduction cascade starting with ligand -stimulated G protein-coupled receptors (GPCRs). [1][2] GPCRs in turn release activated G-protein ...

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

G protein-gated inwardly rectifying potassium (GIRK) channels hyperpolarize neurons in response to activation of many dgirkifferent G protein-coupled receptors and thus control the excitability of neurons through GIRK-mediated self-inhibition, slow synaptic potentials and volume transmission.
