Gap junction channels are composed of members of a multi-gene family of proteins called connexins. These proteins are named by the abbreviation Cx followed by the molecular weight of the specific protein. Mammalian cardiac myocytes express Cx43, Cx45, and Cx40, the former being the major cardiac gap junction protein, which is expressed in atrial and ventricular myocytes as well as in selected regions of the atrioventricular conduction system [1,2]. Individual gap junction channels (also called connexons) formed by multiple connexin
