The article reveals the method of assignment of the Aquaporin-8 water channel gene (AQP8) to human chromosome 16p12. Aquaporins represent water channel proteins widely spread throughout nature where they are responsible for the high water permeability characterizing numerous plasma membranes. Interest is triggered in the recent discovery of the Aquaporin-8 water channel (AQP8) in rat, mouse and human tissues where its distribution predicts roles in secretion of pancreatic juice, bile and primary saliva and in the movement of water across the spermatozoa plasma membrane. The article concludes by stating the location of AQP8 on chromosome 7F3 in humans.
