This gene is a member of the connexin gene family. The encoded protein is a component of gap junctions, which are;composed of arrays of intercellular channels that provide a route for the diffusion of low molecular weight materials;from cell to cell. Mutations in this gene may be associated with atrial fibrillation. Alternatively spliced transcript;variants encoding the same isoform have been described.
