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 {ECO:0000256|RuleBase:RU000630}.
CC -!- SUBUNIT: A connexon is composed of a hexamer of connexins.
CC {ECO:0000256|RuleBase:RU000630}.
CC -!- SUBCELLULAR LOCATION: Cell junction, gap junction
CC {ECO:0000256|ARBA:ARBA00004610}. Cell membrane
CC {ECO:0000256|ARBA:ARBA00004651, ECO:0000256|RuleBase:RU000630}; Multi-
CC pass membrane protein {ECO:0000256|ARBA:ARBA00004651,
CC ECO:0000256|RuleBase:RU000630}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the connexin family.
CC {ECO:0000256|RuleBase:RU000630}.
