Beschreibung

Application

GAP-27 has been used as a blocking peptide for Cx43 (connexin 43) gap junctions in FDC (follicular dendritic cells)-B cell cultures.[1]

Biochem/physiol Actions

GAP-27 shares homology with a region of extracellular loops of connexins, and hence, is thought to inhibit junctions formed by the connexins Cx32, Cx40 and Cx43. It highly hinders co-operative cell-cell interactions including the synergized beating of embryonic cardiomyocytes. This peptide reduces osteoclastic activity and survival rates.[2] This peptide significantly reduces acetylcholine-mediated hyperpolarization of smooth muscle cells.[3]

Inhibitor of gap junction signaling in endothelial cells.
