AQP2 Forms a water-specific channel that provides the plasma membranes of renal collecting duct with high permeability to water, thereby permitting water to move in the direction of an osmotic gradient. Plays an essential role in renal water homeostasis. Belongs to the MIP/aquaporin (TC 1.A.8) family. Expressed in collecting tubules in kidney medulla (at protein level) (PubMed:7510718). Detected in kidney (PubMed:7510718). Note: This description may include information from UniProtKB.
