Researchers gain insight into how ion channels control heart and brain electrical activity
Virginia Commonwealth University researchers studying a special class of potassium channels known as GIRKs, which serve important functions in heart and brain tissue, have revealed how they become activated to control cellular excitability.
The findings advance the understanding of the interaction between a family of signaling proteins called G proteins, and a special type of cell membrane ion pore called G protein-sensitive, inwardly rectifying potassium (GIRK) channels. The findings may one day help researchers develop targeted drugs to treat conditions of the heart such as atrial fibrillation.
