Water and ion permeation of aquaporin-1 in planar lipid bilayers. Major differences in structural determinants and stoichiometry.
(American Society for Biochemistry and Molecular Biology, 2001-08-24)
The aquaporin-1 (AQP1) water channel protein is known to facilitate the rapid movement of water across cell membranes, but a proposed secondary role as an ion channel is still unsettled. Here we describe a method to ...
Ion Permeation of AQP6 Water Channel Protein: Single-Channel Recordings After Hg2+ Activation
(American Society for Biochemistry and Molecular Biology, 2002-08-09)
Aquaporin-6 (AQP6) has recently been identified as an intracellular vesicle water channel with anion permeability that is activated by low pH or HgCl2. Here we present direct evidence of AQP6 channel gating using patch ...
Aquaglyceroporin AQP9: solute permeation and metabolic control of expression in liver
(National Academy of Sciences, 2003-03-04)
Aquaglyceroporins form the subset of the aquaporin water channel family that is permeable to glycerol and certain small, uncharged solutes. AQP9 has unusually broad solute permeability and is expressed in hepatocyte plasma ...
Conversion of aquaporin 6 from an anion channel to a water-selective channel by a single amino acid substitution
(National Academy of Sciences, 2005-02-08)
Aquaporin (AQP) 6 belongs to the aquaporin water channel family. Unlike other aquaporins, AQP6 functions not as a water channel but as an anion-selective channel. Single-channel analyses have shown AQP6 to flicker rapidly ...
