Abstract:G-protein-gated inwardly rectifying potassium (Kir3/GirK) channel is the effector of many G-protein-coupled receptors. Its dysfunction has been linked to the pathophysiology of Down syndrome, Alzheimer’s and Parkinson’s diseases, psychiatric disorders, epilepsy, drug addiction, or alcoholism.

Here, in order to elucidate the role of Gir… Show more
