Answer:
Vasopressin has the ability to bind to,and thereby act upon different receptors subtype, which in turn triggers different cellular responses in different tissues.
Explanation:
Vasopressin, also known as ADH, or antidiuretic hormone, is a hormone that is synthesized in hypothalamus and stored in the posterior pituatary gland. Their main function in the body is to maintain the osmolality of the blood, thus maintaining the blood volume. In addition to this, it also controls the internal temperate of the body, and also regulates circardian rythm.
Vasopressin binds to and, and act on different receptors subtypes such as:
•V1(V1A)-located on vascular smooth muscles and also found on myometrium and platelets
•V2-found on the basolateral membrane of the collecting tubules cells of the kidney
•V3(V1B)-mainly located in pituatary
•oxytocin-type receptors-located in the mammary glands, myometrium and endometrium of the uterus, ovary, testis, adrenals, fat cells , liver etc
