CC -!- FUNCTION: Water channel required to facilitate the transport of water
CC across cell membrane. {ECO:0000269|PubMed:14673023}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC protein {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Specifically expressed in roots.
CC {ECO:0000269|PubMed:14673023}.
CC -!- INDUCTION: By salt and osmotic stress. Expressed in roots with a
CC circadian rhythm showing an increase at the end of the night period, a
CC peak during the first part of the light period and then a decrease.
CC {ECO:0000269|PubMed:14673023}.
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. TIP (TC
CC 1.A.8.10) subfamily. {ECO:0000305}.
