Presence of aquaporin and V‐ATPase on the contractile vacuole of <i>Amoeba proteus</i>

Abstract

Our data on ApAQP allow us to provide the first informed explanation of the high water permeability of the CV membrane in amoeba. Moreover, the results suggest that vesicles possessing V-ATPase are involved in generating an osmotic gradient. Based on our findings, we propose a new hypothesis for the mechanism of CV function.
