| Definition | ChEBI: Arg-Gly-Asp is an oligopeptide. |
| General Description | Arg-Gly-Asp (RGD) is an integrin binding site, which belongs to the class of adhesive proteins. It functions as a brain tumor targeting ligand. |
| Biological Activity | synthetic peptides containing the arginine-glycine-aspartate (rgd) were extensively used as inhibitors of integrin-ligand interactions in studies of cell adhesion, migration, growth and differentiation, since the rgd motif is an integrin-recognition motif found in many ligands. |
| Biochem/physiol Actions | Primary sequence involved with the binding of proteins to cell surfaces |
| in vitro | rgd peptide can induce apoptosis in the absence of signals and integrin-mediated cell clustering. previous study demonstrates that rgd peptides promote apoptosis through activation of conformation changes enhancing pro-caspase-3 activation and autoprocessing [1]. |
| in vivo | anima study suggested that the rgd-4c-fitc-peptide bound to both endothelial and tumor cells in vivo and that peptide targeting should allow the delivery of therapeutic drugs to both endothelial and tumor cells [2]. |
