Appearance of Water Channels in Xenopus Oocytes Expressing Red Cell CHIP28 Protein
(American Association for the Advancement of Science, 1992-04-17)
Water rapidly crosses the plasma membrane of red blood cells (RBCs) and renal tubules through specialized channels. Although selective for water, the molecular structure of these channels is unknown. The CHIP28 protein is ...
Cholangiocytes express the aquaporin CHIP and transport water via a channel-mediated mechanism
(National Academy of Sciences, 1994-12-20)
Cholangiocytes line the intrahepatic bile ducts and regulate salt and water secretion during bile formation, but the mechanism(s) regulating ductal water movement remains obscure. A water-selective channel, the aquaporin ...
Molecular cloning and characterization of AqpZ, a water channel from Escherichia coli
(American Society for Biochemistry and Molecular Biology, 1995-12-08)
The aquaporin family of molecular water channels is widely expressed throughout the plant and animal kingdoms. No bacterial aquaporins are known; however, sequence-related bacterial genes have been identified that encode ...
Reconstitution of functional water channels in liposomes containing purified red cell CHIP28 protein
(American Chemical Society, 1992)
The mercury-sensitive residue at cysteine 189 in the CHIP28 water channel
(American Society for Biochemistry and Molecular Biology, 1993-01-05)
Water channels provide the plasma membranes of red cells and renal proximal tubules with high permeability to water, thereby permitting water to move in the direction of an osmotic gradient. Molecular identification of ...
Reconstitution and functional comparison of purified GlpF and AqpZ, the glycerol and water channels from Escherichia coli
(National Academy of Sciences, 2001-02-27)
A large family of membrane channel proteins selective for transport of water (aquaporins) or water plus glycerol (aquaglyceroporins) has been found in diverse life forms. Escherichia coli has two members of this family-a ...
Specialized membrane domains for water transport in glial cells: high resolution immunogold cytochemistry of aquaporin-4 in rat brain
(Copyright held by the original publisher: Journal of Neuroscience, 1997-01-01)
Membrane water transport is critically involved in brain volume homeostasis and in the pathogenesis of brain edema. The cDNA encoding aquaporin-4 (AQP4) water channel protein was recently isolated from rat brain. We used ...
