Mechanisms by which increased Kv3.4 channel expression might increase cell proliferation. Growth factors, such as those present in serum, trigger expression of Kv3.4 channels. The increased expression of Kv3.4 channels then has the potential to impact cell membrane potential, volume regulation, and formation of proliferation-related macromolecular signaling complexes. Changes in membrane potential, or its regulation, could then affect cell calcium signaling, or other membrane potential-sensitive mechanisms. Changes in cell volume, or its regulation, could alter concentrations or associations of signaling molecules, or produce other effects that might enhance proliferation. Finally, Kv.3.4 channels might interact with other signaling proteins involved in proliferation to form unique signaling complexes and in this way promote cell proliferation.
