Upon exposure to osmotic stimuli, AQP1 is phosphorylated and translocates to the cell membrane. After the initial response, the Ca2+/CaMK2 pathway is activated to regulate membrane localization and the activity of AQP1, which leads to a change in cell size and adjustment to the environment. These changes are blocked by the calmodulin antagonist W‐7.
