Oxytocin Associated Neurophysin

Oxytocin-Associated Neurophysin

Vasopressin Associated Neurophysin

Vasopressin-Associated Neurophysin

Carrier proteins for OXYTOCIN and VASOPRESSIN. They are polypeptides of about 10-kDa, synthesized in the HYPOTHALAMUS. Neurophysin I is associated with oxytocin and neurophysin II is associated with vasopressin in their respective precursors and during transportation down the axons to the neurohypophysis (PITUITARY GLAND, POSTERIOR).
