CC -!- FUNCTION: Forms a water channel with a broad specificity. Also
CC permeable glycerol and urea. Mediates passage of a wide variety of
CC small, non-charged solutes including carbamides, polyols, purines, and
CC pyrimidines. {ECO:0000269|PubMed:9733774}.
CC -!- ACTIVITY REGULATION: Channel activity is inhibited by mercury ions and
CC phloretin. {ECO:0000269|PubMed:9733774}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:9733774};
CC Multi-pass membrane protein {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Detected in testis and liver. Detected in immature
CC spermatocytes and in interstitial Leydig cells.
CC {ECO:0000269|PubMed:9733774}.
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). {ECO:0000250|UniProtKB:Q96PS8}.
CC -!- SIMILARITY: Belongs to the MIP/aquaporin (TC 1.A.8) family.
CC {ECO:0000305}.
