Chemical Properties
White to off-white powder
Uses
Arg-Gly-Asp has been used:
- to saturate the cell surface Arg-Gly-Asp (RGD) receptors and inhibit marrow stromal cell (MSC) attachment to peptide modified hydrogel
- in adhesion assay
- in inhibition assay to confirm the β1-integrin-dependency of cell adhesion
- in textile fabrication and RGD textile functionalization
- to engineer a population of human dermal fibroblasts with impaired migration
- to modify glass substrate and evaluate the behavior of human bone marrow mesenchymal stem cells (hBM-MSCs)
- in the cell culture of human mammary epithelial cells
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].
