CC   -!- FUNCTION: Channel that permits osmotically driven movement of water in
CC       both directions. It is involved in the osmoregulation and in the
CC       maintenance of cell turgor during volume expansion in rapidly growing
CC       cells. It mediates rapid entry or exit of water in response to abrupt
CC       changes in osmolarity. {ECO:0000255|HAMAP-Rule:MF_01146}.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_01146}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01146}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01146}.
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:0000255|HAMAP-Rule:MF_01146}.
