Name Gap junction alpha-1 protein
Synonyms
  1. Connexin-43
  2. Cx43
  3. Gap junction 43 kDa heart protein
Gene Name GJA1
Protein Type Enzyme
Biological Properties
General Function Involved in cell communication
Specific 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. May play a critical role in the physiology of hearing by participating in the recycling of potassium to the cochlear endolymph
