an integral membrane protein of the connexin family, alpha-type (group II) subfamily. Hexamers of connexin-43 form connexons, which aggregate together to form gap junctions, through which materials of low MW diffuse from one cell to a neighboring cell. May play a critical role in the physiology of hearing by participating in the recycling of potassium to the cochlear endolymph. Note: This description may include information from UniProtKB.
