Gap 26,197250-15-0,IC-0216779
Gap26 (Val-Cys-Tyr-Asp-Lys-Ser-Phe-Pro-Ile-Ser-His-Val-Arg) is a connexin mimetic peptide, corresponding to residues 63-75 of connexin 43, which is a gap junction blocker.
Connexins, or gap junctions, are a family of structurally-related transmembrane proteins. Gap junctions contain channels that allow the passage of ions and small molecules between adjacent cells molecules. Calcium and inositol phosphates are among the second messengers that can pass through gap junction channels. [1] It was showed that gap26 attenuates rhythmic contractile activity of rabbit arterial smooth muscle (IC50 = 28.4 mM). It also blocks movement of IP3-induced ATP and Ca2+ across connexin hemichannels, i.e. hexameric channels yet to dock with partners in aligned cells and to generate the gap junction cell–cell conduit.
