DESCRIPTION

Also known as CXB2_HUMAN, GJB2. Structural component of gap junctions (PubMed:17551008, PubMed:19340074, PubMed:21094651, PubMed:26753910, PubMed:16849369, PubMed:19384972). Gap junctions are dodecameric channels that connect the cytoplasm of adjoining cells. They are formed by the docking of two hexameric hemichannels, one from each cell membrane (PubMed:17551008, PubMed:19340074, PubMed:21094651, PubMed:26753910). Small molecules and ions diffuse from one cell to a neighboring cell via the central pore (PubMed:21094651, PubMed:16849369, PubMed:19384972). A hemichannel or connexon is composed of a hexamer of connexins. A functional gap junction is formed by the apposition of two hemichannels (PubMed:17551008, PubMed:19340074, PubMed:21094651, PubMed:26753910). Interacts with CNST (PubMed:19864490). Forms heteromeric channels with GJB4 (By similarity).
