Aquaporin-2: Proteins and Enzymes

Aquaporin 2 (AQP2) is a membrane protein that is involved in plasma membrane water transport in the renal collecting duct. Specifically, AQP2 forms a water-specific channel, providing the renal collecting duct plasma membranes with a high permeability to water and thereby permitting osmosis.

Aquaporin-2 antibodies serve as membrane markers and are useful for renal function studies.
