Neurophysin

Neurophysins are carrier proteins which transport hormones from the hypothalamus to the posterior pituitary gland. Neurophysin-1 transports oxytocin and 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.
