The Relevance of GIRK Channels in Heart Function
Among the large number of potassium-channel families implicated in the control of neuronal excitability, G-protein-gated inwardly rectifying potassium channels (GIRK/Kir3) have been found to be a main factor in heart control. These channels are activated

Domain-selective and sex-dependent regulation of learning and memory in mice by GIRK channel activity in CA1 pyramidal neurons of the dorsal hippocampus. [PDF]
G protein-gated inwardly rectifying K+ (GIRK) channels mediate the postsynaptic inhibitory effect of many neurotransmitters in the hippocampus and are implicated in neurological disorders characterized by cognitive deficits.

Calcium Release from Stores Inhibits GIRK
Synaptic transmission is mediated by ionotropic and metabotropic receptors that together regulate the rate and pattern of action potential firing. Metabotropic receptors can activate ion channels and modulate other receptors and channels.

Encephalopathy-causing mutations in Gβ1 (GNB1) alter regulation of neuronal GIRK channels
Summary: Mutations in the GNB1 gene, encoding the Gβ1 subunit of heterotrimeric G proteins, cause GNB1 Encephalopathy. Patients experience seizures, pointing to abnormal activity of ion channels or neurotransmitter receptors.

Distinct regulation of dopamine D2S and D2L autoreceptor signaling by calcium [PDF]
D2 autoreceptors regulate dopamine release throughout the brain. Two isoforms of the D2 receptor, D2S and D2L, are expressed in midbrain dopamine neurons. Differential roles of these isoforms as autoreceptors are poorly understood.
