Aquaporin-5 (AQP-5) is a protein that in humans is encoded by the AQP5 gene.[5][6]
Aquaporin-5 (AQP-5) is a water channel protein. Aquaporins are a family of small integral membrane proteins related to the major intrinsic protein (MIP or AQP0). Aquaporin-5 plays a role in the generation of saliva, tears and pulmonary secretions.[6] AQP0, AQP2, AQP5, and AQP6 are closely related and all map to 12q13.[6]
AQP-5 features a homotetrameric structure embedded in the cell membrane with the center of each monomer acting as a water pore.[7] Each monomer structure is a transmembrane protein which have an asparagine–proline–alanine (NPA) hydrophobic residue embedded in the membrane of the cell. The NPA residue plays a role in water and solute permeability across the membrane of the cell.[7]
