  • FunctionOne 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.
  • Tissue specificityExpressed in multiple organs and tissues, including heart, uterus, ovary, and blood vessel endothelium.
  • Sequence similaritiesBelongs to the connexin family. Alpha-type (group II) subfamily.
  • Cellular localizationCell membrane. Cell junction > gap junction.
