Gap junctions contain channels that allow the passage of ions and small molecules between adjacent cells. This intercellular communication has been implicated in the coordination of cellular responses to intracellular signaling molecules. Connexins are a family of integral membrane proteins that oligomerize to form intercellular channels that are clustered at gap junctions. Connexins share a common transmembrane (TM) topology. Each connexin is thought to contain 4 TM domains, with two extracellular and three cytoplasmic regions. Connexin-mimetic peptides, i.e. peptides that are identical with a short aa sequence on the Cx subunit have recently emerged as tools to block Connexin hemi-channels (CxHcs) with little or no immediate effects on gap junctions. Gap 24 corresponds to aa sequence on the intracellular loop of Cx32. Gap24 inhibits transfer of fluorescent dyes, electrical coupling and synchronized Ca2+ oscillations in smooth-muscle cells by inhibiting CXhc32 and not gap junction.
