This is amino acid sequence of rat C-peptide-1. C-peptide binds specifically to cell surfaces, probably to a G protein-coupled surface receptor, with subsequent activation of Ca2+-dependent intracellular signaling pathways. It also stimulates Na+-K+-ATPase and endothelial nitric oxide synthase activities. Rat C-peptide was found to diminish glucose-stimulated insulin release in rats both in vivo and in vitro.
