[[http://www.uniprot.org/uniprot/AQPZ_ECOLI AQPZ_ECOLI]] Channel that permits osmotically driven movement of water in both directions. It is involved in the osmoregulation and in the maintenance of cell turgor during volume expansion in rapidly growing cells. It mediates rapid entry or exit of water in response to abrupt changes in osmolarity.<ref>PMID:10400575</ref> <ref>PMID:10518952</ref> <ref>PMID:11493683</ref>
