A KCNJ5 gene provides instructions for making a protein that functions as a potassium channel, which means that it transports positively charged atoms (ions) of potassium (K+) into and out of cells. Potassium channels produced from the KCNJ5 gene are found in several tissues, including the adrenal glands, which are small hormone-producing glands located on top of each kidney. In these glands, the flow of ions creates an electrical charge across the cell membrane, which affects the triggering of certain biochemical processes that regulate aldosterone production. Aldosterone helps control blood pressure by maintaining proper salt and fluid levels in the body.
