Aquaporin water channels: atomic structure molecular dynamics meet clinical medicine
(American Society for Clinical Investigation, 2002-06-01)
Quantification of Aquaporin-CHIP water channel protein in microdissected renal tubules by fluorescence-based ELISA
(American Society for Clinical Investigation, 1995-01)
Several transporters have been localized along the nephron by physiological methods or immunocytochemistry. However, the actual abundance of these molecules has not been established. To accomplish this goal, we have developed ...
The Rh polypeptide is a major fatty acid-acylated erythrocyte membrane protein
(American Society for Biochemistry and Molecular Biology, 1988-12-05)
The erythrocyte Rh antigens contain an Mr = 32,000 integral protein which is thought to contribute in some way to the organization of surrounding phospholipid. To search for possible fatty acid acylation of the Rh polypeptide, ...
Loss of perivascular aquaporin 4 may underlie deficient water and K+ homeostasis in the human epileptogenic hippocampus
(National Academy of Sciences, 2005-01-25)
An abnormal accumulation of extracellular K+ in the brain has been implicated in the generation of seizures in patients with mesial temporal lobe epilepsy (MTLE) and hippocampal sclerosis. Experimental studies have shown ...
The human AQP4 gene: definition of the locus encoding two water channel polypeptides in brain
(National Academy of Sciences, 1996-10-01)
The aquaporin family of membrane water transport proteins are expressed in diverse tissues, and in brain the predominant water channel protein is AQP4. Here we report the isolation and characterization of the human AQP4 ...
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 ...
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. ...
Isolation of proteins related to the Rh polypeptides from nonhuman erythrocytes.
(American Society for Clinical Investigation, 1989-01)
It is thought that the Rh antigens may be important in maintaining normal erythrocyte membrane integrity. Despite their name, Rh antigens are serologically present only on human erythrocytes. Rh structural polymorphisms ...
Fast and Selective ammonia transport by aquaporin-8
(American Society for Biochemistry and Molecular Biology, 2007-02-23)
The transport of ammonia/ammonium is fundamental to nitrogen metabolism in all forms of life. So far, no clear picture has emerged as to whether a protein channel is capable of transporting exclusively neutral NH(3) while ...
Differential control of band 3 lateral and rotational mobility in intact red cells
(American Society for Clinical Investigation, 1994-08)
Measurements of integral membrane protein lateral mobility and rotational mobility have been separately used to investigate dynamic protein--protein and protein-lipid interactions that underlie plasma membrane structure ...
