General annotation (Comments)
| Function | One gap junction consists of a cluster of closely packed pairs of transmembrane channels, the connexons, through which materials of low MW diffuse from one cell to a neighboring cell. |
| Subunit structure | A connexon is composed of a hexamer of connexins. |
| Subcellular location | Cell membrane; Multi-pass membrane protein. Cell junction › gap junction. |
| Tissue specificity | Highly expressed in lung. |
| Sequence similarities | Belongs to the connexin family. Alpha-type (group II) subfamily. |
