Connexins are four-transmembrane proteins with two extracellular loops and one intracellular loop. They build hexameric connexons (hemichannels), which dock to a connexon of an adjacent cell forming a complete, dodecameric gap junction channel. M, cell membrane; ES, extracellular space; IS, intracellular space.
