Aquaporin 3 (AQP-3) is the protein product of the human AQP3 gene.^[5] It is found in the basolateral cell membrane of principal collecting duct cells and provides a pathway for water to exit these cells.^[6] Aquaporin-3 is also permeable to glycerol, ammonia, urea, and hydrogen peroxide. It is expressed in various tissues including the skin, respiratory tract, and kidneys as well as various types of cancers.^[7] In the kidney, aquaporin-3 is unresponsive to the antidiuretic hormone vasopressin, unlike aquaporin-2.^[8] This protein is also a determinant for the GIL blood group system.^[9]

Suberoylanilide hydroxamic acid (SAHA) (a HDAC inhibitor) increases expression of aquaporin-3 in normal skin cells (keratinocytes).^[10]
