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 (PubMed: 8140421, PubMed: 7524315, PubMed: 7510718, PubMed: 15509592). Plays an essential role in renal water homeostasis (PubMed: 8140421, PubMed: 7524315, PubMed: 15509592)
