CC -!- FUNCTION: Water channel required to facilitate the transport of water
CC across membranes. Involved in freeze tolerance, osmotolerance and cell
CC flocculation in liquid cultures (By similarity). Is non-functional in
CC most laboratory strains. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000269|PubMed:14562095}; Multi-pass membrane protein
CC {ECO:0000269|PubMed:14562095}. Cell membrane {ECO:0000250}; Multi-pass
CC membrane protein {ECO:0000269|PubMed:14562095}.
CC -!- INDUCTION: During exponential phase in rich medium and repressed in
CC minimum medium, hyper-osmolar medium or in sporulating conditions.
CC {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.
CC {ECO:0000305}.
CC -!- CAUTION: This is a truncated version of aquaporin-2. In strain S288c
CC and many laboratory strains, a natural 11 bp deletion in position 109
CC leads to a frameshift, which disrupts the gene coding for this protein
CC and produces two ORFs YLL052C and YLL053C. A contiguous sequence for
CC aquaporin-2 can be found in strain Sigma 1278B (AC P0CD89).
CC {ECO:0000305}.
