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. 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.

Application

Gly-Arg-Gly-Asp-Ser-Pro-Lys (RGD peptide) has been used-
  • as a blocking peptide to inhibit integrin-fibronectin binding
  • in adhesion assay performed on porcine trophectoderm to study the influence of TGFβ (transforming growth factor) on cell adhesion
  • for incubation of MC3T3-E1 osteoblast cells to determine its effect on cell adhesion measured by AFM (atomic force microscopy)
  • for the preparation of RGD.Flt23k.NR nanoparticles
  • to determine the involvement of RGD-integrin bonding in cell adhesion process

Biochem/physiol Actions

Fibronectin analog that binds to integrins.

The secretion of fibronectin by differentiating osteoblasts and its accumulation at sites of osteogenesis suggest that fibronectin participates in bone formation. To test this directly, we determined whether fibronectin-cell interactions regulate progressive differentiation of cultured fetal rat calvarial osteoblasts. Spatial

Neovascularization (NV) of the cornea can disrupt visual function, causing ocular diseases, including blindness. Therefore, treatment of corneal NV has a high public health impact. Epigalloccatechin-3-gallate (EGCG), presenting antiangiogenesis effects, was chosen as an inhibitor to treat human vascular endothelial

Since osteoblast proliferation is critical for bone development, the effect of bone extracellular matrix (ECM) proteins on osteoblast signaling and proliferation in serum-free medium was investigated. Proliferation was highest in primary rat calvarial osteoblasts cells grown on fibronectin but less

Developmental processes in multicellular organisms require structural elements, such as adhesion molecules, to stabilize cells at functional positions. In vertebrates, a series of extracellular matrix proteins, e.g. fibronectin and laminin, are involved in cell adhesion. These proteins contain Arg-Gly-Asp [RGD]
