ETB receptor

The ETB receptor is a type of protein found on the surface of certain cells in the body that specifically interacts with a molecule called endothelin-1. When endothelin-1 binds to the ETB receptor, it triggers a response inside the cell, such as regulating blood vessel constriction, cell growth, or other functions. These receptors are important for maintaining blood pressure and blood flow, and they also play roles in health and disease, including conditions like hypertension or vascular disorders. They are part of the body’s complex system for controlling and responding to blood vessel signals.
