[5][6] This gene is a member of the connexin gene family.

The encoded protein is a component of gap junctions, which are composed of arrays of intercellular channels that provide a route for the diffusion of low molecular weight materials from cell to cell.

Alternatively spliced transcript variants encoding the same isoform have been described.
