Abstract© 2015 by The American Society for Biochemistry and Molecular Biology, Inc. Background: The water channel protein aquaporin 4 (AQP4) controls water permeability of the blood-brain barrier. Results: Hypotonicity induces rapid relocalization of AQP4 in a calcium-, calmodulin-, and kinase-dependent manner. Conclusion: AQP4 can be relocalized between the cell membrane and intracellular compartments. Significance: Pharmacological modulation of AQP4 membrane localization could provide a new approach to treating brain edema.
