Some of the diseases associated with connexons are cardiovascular disease and diabetes, which is the inability of the body to produce insulin for glucose uptake by cells and degradation in the smaller units of connexons, called connexins, possibly leading to the onset of heart disease. Cardiovascular disease and diabetes, type I and II, affects similar locations within cells of the heart and pancreas. This location is the gap junction, where connexons facilitate rapid cell-to-cell interactions via electrical transmissions. Gap junctions are often present at nerve endings such as in cardiac muscle and are important in maintaining homeostasis in the liver and proper function of the kidneys. The gap junction itself is a structure that is a specialized transmembrane protein formed by a connexon hemichannel. Cardiovascular disease and possibly type I and II diabetes, are each associated with a major protein connexin that makes up the gap junction.
