Gonadotropin-releasing hormone (GnRH) receptors are integral membrane proteins primarily found in the anterior pituitary gland. These receptors play a crucial role in the regulation of reproductive functions. They bind to GnRH, a decapeptide hormone produced by the hypothalamus, to initiate a cascade of intracellular events that ultimately lead to the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
