Regulation of aquaporin-2 water channel trafficking by vasopressin
Curr Opin Cell Biol.
1997 Aug.
Abstract
Vasopressin regulates water excretion from the kidney by increasing the osmotic water permeability of the renal collecting duct. The aquaporin-2 water channel has been demonstrated to be the target for this action of vasopressin. Recent studies have demonstrated that vasopressin, acting through cyclic AMP, triggers fusion of aquaporin-2-bearing vesicles with the apical plasma membrane of the collecting duct principal cells. The vesicle-targeting proteins synaptobrevin-2 and syntaxin-4 are proposed to play roles in this process.
