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: A connexon is composed of a hexamer of connexins.
SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein. Cell junction, gap junction.
TISSUE SPECIFICITY: Eye lens.
SIMILARITY: Belongs to the connexin family. Alpha-type (group II) subfamily.
