CC -!- FUNCTION: Aquaporin required to facilitate the transport of water from
CC the vacuolar compartment to the cytoplasm. Does not promote glycerol
CC permeability. Its function is impaired by Hg(2+). Transports urea in
CC yeast cells and Xenopus laevis oocytes in a pH-independent manner.
CC Transports methylammonium or ammonium in yeast cells and Xenopus laevis
CC oocytes, preferentially at high medium pH. May participate in vacuolar
CC compartmentation and detoxification of ammonium.
CC {ECO:0000269|PubMed:14576283, ECO:0000269|PubMed:15665250,
CC ECO:0000269|PubMed:8624437}.
CC -!- SUBUNIT: Interacts with cucumber mosaic virus (CMV) Protein 1a.
CC {ECO:0000269|PubMed:17030879}.
CC -!- INTERACTION:
CC Q41951; Q41951: TIP2-1; NbExp=2; IntAct=EBI-4442669, EBI-4442669;
CC -!- SUBCELLULAR LOCATION: Vacuole membrane {ECO:0000269|PubMed:10737809,

CC ECO:0000269|PubMed:8624437}. Note=Tonoplast. It is specifically located
CC in the tonoplast of protein storage vacuoles (PSV) (By similarity).
CC {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Strongly expressed in shoot, rosette, bolt and
CC flowers. Also expressed in roots, flower buds and above ground.
CC {ECO:0000269|PubMed:11806824, ECO:0000269|PubMed:8624437}.
CC -!- DEVELOPMENTAL STAGE: Starts to be expressed in seedlings from 2 days
CC ays after germination. {ECO:0000269|PubMed:14576283}.
CC -!- INDUCTION: By ammonium nitrate in roots. Expressed in roots with a
CC circadian rhythm showing an increase after onset of light, a peak
CC approximately at midday and a decline to lowest levels before offset of
CC light. {ECO:0000269|PubMed:15665250}.
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}.
CC -!- CAUTION: Was originally assigned as At3g16230, which is now a
CC completely different protein not related to aquaporins. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAA79093.1; Type=Erroneous initiation; Evidence={ECO:0000305};
CC Sequence=CAA82298.1; Type=Erroneous initiation; Evidence={ECO:0000305};
