Each cell in your body relies on precise communication with other cells to function properly. At the center of this process are the molecular switches that turn communication signals in the body on and off. These molecules are key players in health and disease. One such molecular switch is G protein-coupled receptor kinases, or GRKs for short. From vision to heart function and cell growth, GRKs play a vital role in maintaining physiological balance. When they go awry, they can contribute to cardiovascular disease, inflammatory illnesses like rheumatoid arthritis and multiple sclerosis, neurodegenerative diseases like Alzheimer’s, and multiple types of…
