CC   -!- FUNCTION: Water channel required to facilitate the transport of water
CC       across membranes. Involved in osmotolerance (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC       protein {ECO:0000250}.
CC   -!- DOMAIN: Aquaporins contain two tandem repeats each containing three
CC       membrane-spanning domains and a pore-forming loop with the signature
CC       motif Asn-Pro-Ala (NPA).
CC   -!- SIMILARITY: Belongs to the MIP/aquaporin (TC 1.A.8) family.
CC       {ECO:0000305}.
