Human red cell Aquaporin CHIP. II. Expression during normal fetal development and in a novel form of congenital dyserythropoietic anemia
(The American Society for Clinical Investigation, 1994-09)
Channel-forming integral protein (CHIP) is the archetypal member of the Aquaporin family of water channels. Delayed CHIP expression was shown recently in perinatal rat (Smith, B. L., R. Baumgarten, S. Nielsen, D. Raben, ...
Secretin promotes osmotic water transport in rat cholangiocytes by increasing aquaporin-1 water channels in plasma membrane: Evidence for a secretin-induced vesicular translocation of aquaporin-1
(American Society for Biochemistry and Molecular Biology, 1997-05-16)
Although secretin is known to stimulate ductal bile secretion by directly interacting with cholangiocytes, the precise cellular mechanisms accounting for this choleretic effect are unknown. We have previously shown that ...
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 ...
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 ...
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)
Water channel properties of major intrinsic protein of lens
(American Society for Biochemistry and Molecular Biology, 1995-04-14)
The functions of major intrinsic protein (MIP) of lens are still unresolved; however the sequence homology with channel-forming integral membrane protein (CHIP) and other Aquaporins suggests that MIP is a water channel. ...
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 ...
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 ...
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 ...
