Catalog Number: 1950
Biological Activity
Peptide, corresponding to residues 63 - 75 of connexin 43, which is a gap junction blocker. Attenuates rhythmic contractile activity of rabbit arterial smooth muscle (IC50 = 28.4 μM). Also inhibits IP3-induced ATP release, without inhibiting gap junctional coupling in endothelial cells.
