Vasopressin functions as an antidiuretic hormone. It is naturally produced by the pituitary gland and has an effect on the kidneys and blood vessels. Vasopressin is used to treat diabetes insipidus and some stomach issues after surgery or during abdominal x-rays. It is injected into a muscle, beneath the skin, or into a vein.
What is the function of vasopressin?
Vasopressin (also known as an antidiuretic hormone) regulates the circadian rhythm or the times of sleep and wakefulness in a 24-hour cycle. Vasopressin also aids in the regulation of the body's internal temperature, blood volume, and the flow of urine from the kidneys.
What is another name for vasopressin?
Vasopressin is marketed under several brand names, including Vasostrict and ADH.
What does vasopressin do to blood?
AVP increases water permeability in renal collecting ducts via V2 receptors (a cAMP-dependent mechanism), resulting in reduced urine production (hence, the antidiuretic action of "antidiuretic hormone"). Blood volume, cardiac output, and arterial pressure all rise as a result of this.
Three-vasopressin receptors are heptahelical membrane proteins that activate intracellular effectors via G-protein activation. The sensitivity of the VlaR protein to cellular proteases has impeded the biochemical characterization of the protein. The presence of hundreds of naturally occurring mutations capable of inactivating the V2R provides a unique source of information for evaluating the impact of missense mutations on serpentine receptor function.
