AQP7
Aquaporin-7 is a protein that in humans is encoded by the AQP7 gene.[5][6]
Aquaporins/major intrinsic protein (MIP) are a family of water-selective membrane channels. Aquaporin 7 has greater sequence similarity with AQP3 and AQP9 and they may be a subfamily. Aquaporin 7 and AQP3 are at the same chromosomal location suggesting that 9p13 may be a site of an aquaporin cluster. Aquaporin 7 facilitates water, glycerol and urea transport. It may play an important role in thermoregulation in the form of perspiration and sperm function.[6]
