| description | The aquaporins (AQPs) are a family of integral membrane proteins composed of two subfamilies: the orthodox aquaporins, which transport only water, and the aquaglyceroporins, which transport glycerol, urea, or other small solutes []. AQP1 in pleural mesothelial cells participate in the formation of pleural fluid [], renal AQP2 is involved in levels of solutes []and changes in AQP9 in the hippocampus are related to delayed neuronal death []. Aquaporins contain two tandem repeats, each containing three membrane-spanning domains and a pore-forming loop with the signature motif Asn-Pro-Ala (NPA).Aquaporin-11 (AQP11) and aquaporin-12 belong to a new aquaporin subfamily termed superaquaporins []. AQP11 is found in the endoplasmic reticulum and has been connected to policystic kidney disease through knock-out experiments []. It has also been shown that although the characteristic NPA motif may not be fully conserved in both tandem repeats, the molecule nevertheless preserves its water-transport function []. |
