CC -!- FUNCTION: Water channel required to facilitate the transport of water
CC across cell membrane. Inactive in yeast cells.
CC {ECO:0000269|PubMed:16223486}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000305};
CC Multi-pass membrane protein {ECO:0000305}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=1;
CC Comment=A number of isoforms are produced. According to EST
CC sequences.;
CC Name=1;
CC IsoId=Q9M1K3-1; Sequence=Displayed;
CC -!- TISSUE SPECIFICITY: Expressed in dividing cells and elongating regions
CC of the root tips, emerging lateral roots, root steles, cotyledons, main
CC veins of the rosette leaves, vascular tissues of the flower petals,
CC stigma, stamens (anthers and filaments), pollen and the top and bottom
CC (receptacle) of siliques. {ECO:0000269|PubMed:11806824,
CC ECO:0000269|PubMed:16223486}.
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/Leu (NPA).
CC -!- SIMILARITY: Belongs to the MIP/aquaporin (TC 1.A.8) family. SIP (TC
CC 1.A.8.10) subfamily. {ECO:0000305}.
