Aquaporins (AQPs) are integral membrane proteins that form pores in the membrane of biological cells. At least 13 mammalian AQPs (AQP0–AQP12) have been identified and divided into two groups on the basis of their permeability. AQPs 1, 2, 4, 5 and 8 function primarily as water-selective transporters; AQPs 3, 7, 9 and 10, termed aquaglyceroporins, transport water as well as glycerol and possibly other small solutes.
