Term Name: gap junction channel activity
Synonyms: connexin, innexin, innexin channel activity, intercellular channel
Definition: A wide pore channel activity that enables a direct cytoplasmic connection from one cell to an adjacent cell. The gap junction can pass large solutes as well as electrical signals between cells. Gap junctions consist of two gap junction hemi-channels, or connexons, one contributed by each membrane through which the gap junction passes.
