Neurophysin

Function Neurophysins are carrier proteins which transport hormones from the hypothalamus to the posterior pituitary gland. Neurophysin-1 transports oxytocin. Neurophysin-2 transports vasopressin. Oxytocin is used to start labor and increase its speed. Vasopressin functions to retain water in the body and to constrict blood vessels. Disease Mutations in neurophysin-2 are associated with familial diabetes. Structural highlights .
