Definition
ADH is an antidiuretic hormone released by the hypothalamus and stored in the posterior pituitary gland.
Features
ADH is a nonapeptide released as prohormone (prepropressophysin) by the hypothalamus in storage vesicles. In the Golgi apparatus, the signal peptide portion is cleaved from prepropressophysin to produce a prohormone that is stored in secretory vesicles transported through the hypothalamic-hypophysial tract where they are ultimately released in the posterior pituitary. In detail, prepropressophysin contains a signal peptide, neurophysin II, and a glycoprotein. The signal peptide is removed in the Golgi apparatus to produce a prohormone stored in secretory vesicles. During the translocation to the posterior pituitary gland, the prohormone is cleaved to produce ADH (Cuzzo and Lappin 2019).
ADH plays an important role in body’s osmotic balance, blood pressure, and kidney function regulation. Once released, ADH binds its type-2...
