Cftr physiological function
Web21 hours ago · Under physiological conditions, the precise orchestration of hypothalamic kisspeptin neurons and gonadotropin-releasing hormone (GnRH) neurons induces the secretion of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary, which in turn initiates gonadal steroid production that regulates … WebThe CFTR gene provides instructions for making a protein called the CF transmembrane conductance regulator (CFTR). This protein functions as a channel across the membrane of cells that produce mucus, sweat, saliva, tears, and digestive enzymes. The channel transports negatively charged particles called chloride ions into and out of cells. The ...
