Water is a critical component of all living cells.
Tissue membranes show a great degree of water permeability.
Mammalian red cells, renal proximal tubules, and descending thin limb of Henle are extraordinarily permeable to water.
Water crosses hydrophobic plasma membranes either by simple diffusion or through a facilitative transport mechanism mediated by "aquaporin".
Genes for several members of aquaporin family have been cloned, expressed, and their distribution studied in many tissues.
AQP0 or MIP26 (major intrinsic protein 26kD), and Aquaporin-1 (AQP1, purified from red cells) also called CHIP-28 (channel forming integral protein, 28kD; 268aa; gene locus 7p14) has been the foundation of the growing family of aquaporins.
The lens specific AQP0 represents up to 80% of total lens membrane protein.
Defects in MIP26 are cause of autosomal dominant cataract.
The cataract Fraser mutation (CAT-FR or Shriveled) is a trans- poson-induced splicing error that substitutes a long terminal repeat sequence for the c-terminus of MIP.
The lens opacity mutation (LOP) is an aa substitution that inhibits targeting of MIP to the cell membrane.
AQP5 (282aa) is found in several epithelial tissues (salivary and lachrymal glands, corneal epithelium in the eye and lung).
It is implicated in generation of saliva, tears, and pulmonary secretions.
AQP families of proteins are predicted to contain six transmembrane domains.
Rat-AQP5 is a 265 amino acid transmembrane protein.
