Kv2.1 is expressed in the brain (cell bodies and dendrites of neurons but not axons, as well as Schwann cells), atria, ventricle, skeletal muscle, cochlea, retina, lung and pulmonary arteries. It is involved in maintaining membrane potential and modulating electrical excitability of both neurons and muscle cells. It is thought that Kv2.1 has a role in the muscle tone of the pulmonary system, as the expression Kv2.1 in pulmonary smooth muscle has been found to be reduced in chronic hypoxic pulmonary hypertension.
