Arginyl-Glycyl-Aspartic Acid is a tripeptide composed of L-arginine, glycine, and L-aspartic acid, used as a biochemical tool in the study of cellular recognition. Arginylglycylaspartic acid hows great affinity for the integrin receptors and Arg-Gly-Asp tripeptide motif can be used for Peptide-Based Target Drug Delivery of anticancer agents. The tripeptide Arg-Gly-Asp (RGD) is an important protein sequence in the binding of proteins to cell surfaces. The RGD motif was identified in fibronectin, vitronectin, osteopontin, collagens, thrombospondin, fibrinogen, and von Willebrand factor. Many adhesive extracellular matrix, blood, and cell surface proteins recognize the RGD sequence for cell attachment.
