Function: Neurophysin 2 specifically binds vasopressin.; Vasopressin has a direct antidiuretic action on the kidney, it also causes vasoconstriction of the peripheral vessels. Acts by binding to vasopressin receptors (V1bR/AVPR1B, V1aR/AVPR1A, and V2R/AVPR2) (By si
Mechanism: Fetal neurophysin is the major neurophysin present in the neurohypophysis of 7 to 9 month fetuses and its sequence appears to be identical with that of the adult.
