Caption
This is a cross section of a potassium channel in a smooth muscle cell of the pulmonary artery. A study by Dr. Wendy Chung has identified six new mutations in a gene called KCNK3 that can interfere with the function of potassium channels and lead to pulmonary hypertension. The mutations are depicted in color at the locations where they exert their effects.
