RT erythroblasts.";
RL Biochim. Biophys. Acta 1463:374-382(2000).
CC -!- FUNCTION: Forms a water-specific channel that provides the plasma
CC membranes of red cells and kidney proximal tubules with high
CC permeability to water, thereby permitting water to move in the
CC direction of an osmotic gradient. {ECO:0000269|PubMed:10675514}.
CC -!- SUBUNIT: Homotetramer (By similarity). Interacts with EPHB2; involved
CC in endolymph production in the inner ear. Identified in a complex with
CC STOM (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:10675514};
CC Multi-pass membrane protein {ECO:0000269|PubMed:10675514}.
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 -!- MISCELLANEOUS: Pharmacologically inhibited by submillimolar
CC concentrations of mercury. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the MIP/aquaporin (TC 1.A.8) family.
CC {ECO:0000305}.
