What is a insulin receptor?

An insulin receptor is a transmembrane protein found on the surface of cells that binds insulin, a hormone that regulates glucose metabolism. Upon binding insulin, the receptor undergoes a conformational change that activates intracellular signaling pathways, promoting glucose uptake by cells and influencing various metabolic processes. This interaction is crucial for maintaining normal blood sugar levels and overall metabolic health. Dysregulation of insulin receptors can lead to conditions like insulin resistance and type 2 Diabetes.
