Detailed explanation-1: -It is found in the kidneys in structures called collecting ducts, which are a series of small tubes that reabsorb water from the kidneys into the bloodstream. The aquaporin 2 water channel plays an essential role in maintaining the body’s water balance.
Detailed explanation-2: -Aquaporin-2 is the only water channel that is activated by vasopressin to enhance water reabsorption in the kidney collecting duct. Aquaporin-3 also contributes to water reabsorption in the kidney collecting duct but is unresponsive to vasopressin. It also appears that aquaporin-3 may contribute to cornea transparency.
Detailed explanation-3: -Aquaporin-2 (AQP-2) is found in the apical cell membranes of the kidney’s collecting duct principal cells and in intracellular vesicles located throughout the cell.
