RT   "Aquaporins constitute a large and highly divergent protein family in
RT   maize.";
RL   Plant Physiol. 125:1206-1215(2001).
CC   -!- FUNCTION: Aquaporins facilitate the transport of water and small
CC       neutral solutes across cell membranes. {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. PIP (TC
CC       1.A.8.11) subfamily. {ECO:0000305}.
