The structure of one of the four subunits of the water-channel protein AQP1, embedded in the cell membrane. Each unit contains an independent water pore (marked by blue dots). A wide "vestibule" outside the cell (top) leads to the pore, which is about 2.8 angstroms across at its narrowest, just wide enough to admit water molecules. The pore widens into another vestibule inside the cell (bottom).
