Connexins, such as GJB7, are involved in the formation of gap junctions, intercellular conduits that directly connect the cytoplasms of contacting cells. Each gap junction channel is formed by docking of 2 hemichannels, each of which contains 6 connexin subunits.GJB7 (Gap Junction Protein Beta 7) is a Protein Coding gene. Among its related pathways are Vesicle-mediated transport and Gap junction trafficking. An important paralog of this gene is GJB5.
