Description

Amino Acid Sequence

Gly-Arg-Gly-Asp-Ser-Pro-Lys

General description

Gly-Arg-Gly-Asp-Ser-Pro-Lys is a RGD peptide. Naturally occurring RGD peptides, present in the ECM (extracellalar matrix) proteins, are involved in facilitating integrin-mediated cell adhesion to matrix proteins.[1] RGD peptide is present as repeats in cell-adhesion protein, such as fibronectin and vitronectin. This tripeptide is recognized by cells by specific integrins (e.g. β1 , β3 , and β5 subunits), present on the cell surface and associated with the actin filament via the FA (focal adhesion)-complex.[2]

Application

Gly-Arg-Gly-Asp-Ser-Pro-Lys (RGD peptide) has been used-

• as a blocking peptide to inhibit integrin-fibronectin binding[3]
• in adhesion assay performed on porcine trophectoderm to study the influence of TGFβ (transforming growth factor) on cell adhesion[4]
• for incubation of MC3T3-E1 osteoblast cells to determine its effect on cell adhesion measured by AFM (atomic force microscopy)[2]
• for the preparation of RGD.Flt23k.NR nanoparticles[5]
• to determine the involvement of RGD-integrin bonding in cell adhesion process[6]

Biochem/physiol Actions

Fibronectin analog that binds to integrins.
