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 ...
Localization of aquaporin CHIP in the human eye: implications in the pathogenesis of glaucoma and other disorders of ocular fluid balance
(Association for Research in Vision and Ophthalmology, 1994-10)
PURPOSE. The existence of integral membrane proteins that serve as selective water channels has been postulated to explain the movement of water across plasma membranes. Aquaporin CHIP (channel-forming integral membrane ...
Biologically active two-dimensional crystals of aquaporin CHIP
(American Society for Biochemistry and Molecular Biology, 1994-01-21)
Plasma membranes of several mammalian tissues are highly permeable to water due to the presence of CHIP, the 28-kDa channel-forming integral protein which is the archetypal member of the aquaporin family of water channel ...
Genomic organization and developmental expression of aquaporin-5 in lung
(American College of Chest Physicians, 1997-06)
Molecular struture of the water channel through aquaporin CHIP. The hourglass model.
(American Society for Biochemistry and Molecular Biology, 1994-05-20)
Aquaporin channel-forming integral protein (CHIP) is the first characterized water channel protein (genome symbol AQP1), but the molecular structure of the aqueous pathway through CHIP remains undefined. The two halves of ...
Aquaporin-1 Water Channel Expression in Human Kidney
(American Society for Nephrology, 1997-01)
The pattern of aquaporin-1 water channel protein (AQP1) expression in the human kidney was analyzed by immunocytochemistry using semi-thin and optimized high-resolution immunoelectron microscopy based on freeze-substituted ...
Direct immunogold labeling of aquaporin-4 in square arrays of astrocyte and ependymocyte plasma membranes in rat brain and spinal cord
(National Academy of Sciences, 1998-09-29)
Aquaporin (AQP) water channels are abundant in the brain and spinal cord, where AQP1 and AQP4 are believed to play major roles in water metabolism and osmoregulation. Immunocytochemical analysis of the brain recently ...
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 ...
Isolation of the cDNA for erythrocyte integral membrane protein of 28 kilodaltons: member of an ancient channel family
(National Academy of Sciences, 1991-12-15)
CHIP28 is a 28-kDa integral membrane protein with similarities to membrane channels and is found in erythrocytes and renal tubules. A cDNA for CHIP28 was isolated from human fetal liver cDNA template by a three-step ...
Regulation of the Escherichia coli water channel gene aqpZ
(National Academy of Sciences, 1998-03-31)
Osmotic movement of water across bacterial cell membranes is postulated to be a homeostatic mechanism for maintaining cell turgor. The molecular water transporter remained elusive until discovery of the Escherichia coli ...
