Biochem/physiol Actions
Gap19, nonapeptide from the cytoplasmic loop of Connexin-43, is a selective blocker of connexin 43 (Cx43) hemichannel that does not block GJ or Cx40/Panx-1 channels in cardiomyocytes and astrocytes. Gap19 prevents Cx43 hemichannel opening and protect against myocardial ischemia/reperfusion injury.
