Aquaporin-4 is a transmembrane water channel protein, the C-terminal domain of which facing cytosol. In process investigating role aquaporin-4 with regard to intracellular trafficking, we observed that derivative aquaporin-4, in 53 amino acids had been removed (?271-323), was localized compartments, including endoplasmic reticulum, but not expressed on plasma membranes. This determined by immun...
