CC -!- FUNCTION: One gap junction consists of a cluster of closely packed
CC pairs of transmembrane channels, the connexons, through which materials
CC of low MW diffuse from one cell to a neighboring cell.
CC -!- SUBUNIT: A connexon is composed of a hexamer of connexins. Interacts
CC with CNST. {ECO:0000269|PubMed:19864490}.
CC -!- SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein. Cell
CC junction, gap junction.
CC -!- DISRUPTION PHENOTYPE: Mice lacking both Gja12 and Gjb1 display a severe
CC demyelination phenotype associated with oligodendrocyte death. These
CC mice develop action tremors, tonic seizures, sporadic convulsions and
CC loss of consciousness preceding death in the sixth week after birth.
CC {ECO:0000269|PubMed:12843301}.
CC -!- SIMILARITY: Belongs to the connexin family. Beta-type (group I)
CC subfamily. {ECO:0000305}.
