Connexin mimetic peptide 40GAP27

Connexin mimetic peptide 40GAP27, corresponding to the GAP27 domain of the second extracellular loop of the dominant vascular connexin (Cx40), designated as 40Gap27, is a biologically active peptide utilized to study the pathways by which oxidant stress hinders gap junction communication. Administered 40Gap27 attenuates endothelium-dependent subintimal smooth muscle hyperpolarization.
