As you mentioned water is a dielectric and because of that and the presence of ions in solution, electrostatic forces have a very short range inside a cell. If you apply a potential difference (voltage) in solution, you will generate a constant electric field between the two electrodes. Proteins will respond to this electric field by moving towards the ...

There are various proteins sensitive to changes in electric field. More precisely, they are activated by changes in voltage (surrounding the protein), and immersed in water, as all cells are mainly composed of an aqueous solution. You are correct that most charges in the side chains of the proteins' amino acids are 'masked' by the dipole character of water ...
