| Function
Neurophysins are carrier proteins which transport hormones from the hypothalamus to the posterior pituitary gland[1].
- 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[2].
