Glucagon Receptor

The glucagon receptor is a protein found on certain cells, mainly in the liver, that detects and responds to glucagon, a hormone that raises blood sugar levels. When blood sugar is low, glucagon binds to this receptor, triggering processes that release stored sugar into the bloodstream. This helps maintain healthy blood glucose levels, providing energy to the body. The receptor acts as a communication point, translating the message from glucagon into a biological response to ensure your blood sugar stays balanced, especially during fasting or between meals.
