Definition:
A protein found on the surface of cells that binds to the hormone oxytocin, triggering various physiological responses. These receptors are primarily located in the uterus, mammary glands, brain, and other tissues involved in reproduction and social interactions. The activation of oxytocin receptors helps coordinate functions like labor, emotional bonding, and even responses to stress. The gene encoding the oxytocin receptor is called OXTR.
